Eliza nodded and scribbled out the four and put it in the wrong place. "These things are god-awful. Why do you make us do them?" she asked, moving down the column of numbers and mentally checking her math.

"Because you need to learn it. It's a good thing to know." Hermione twirled a strand of hair around her finger. "Your father used to help me on my more advanced Arithmancy homework, you know."

Eliza straightened up. Neither one of her parents ever spoke of their courtship. "How much older is Daddy than you?" That was another great mystery. Neither one of them spoke of how old her father was. Sure, Eliza knew that her mother was thirty-three, but she was never too sure as to how older her father was.

"Ah, there's something you'll have to ask him. Now, are you almost finished? It's about time for you to go back to Gryffindor." Hermione was purposefully not catching Eliza's eye as her daughter gathered her stuff up and left.

"My parents are the biggest enigma in my life," Eliza complained the next morning over breakfast. "Like, the basic stuff such as age. I know how old Mum is, but Daddy refuses to tell me how old he is. And Mum isn't sharing that knowledge, either."

"You're so worked up over ages?" Jack asked, smearing jelly over a biscuit. "Why don't you try to find some information on your Dad? I'm sure he's written up somewhere in the library. Or, if you really like, ask my dad. I’m sure he can tell you."

"Well, it's not just ages..it's stuff like why they mysteriously leave the house in the middle of the week for days on end. And like why I'm not allowed into the third floor of our house."

"Why don't you just ask?" Jacob asked.

"Because when I do, they say something like 'Isn't it time for you to go to bed?' or 'Don't you have homework?' Those two are harder to get information out of than the Unspeakables."

"Then I suppose it's not fun to be you. Now, we've got approximately five minutes to get down to the dungeons for Potions," Jack said, standing and grabbing his bag. "I suggest we leave now."

"Good idea," Eliza said, doing the same. "I don't really want to be in MORE trouble."

Jack and Jacob laughed at her and Eliza glared. The two guys stopped laughing; Eliza had a glare much like her father's glare. Of course, it didn't help much that she look almost exactly like him (excepting her brown eyes, of course). After leaving the Great Hall, they walked in semi-silence down to the cold, damp dungeons.

In the dungeons, Jack, Jacob, and Eliza took their seats in the front-left of the room. Their spot was least visible from Snape's vantage point while he lectured. Therefore, it was the perfect place to plan pranks and jokes. However, Snape seemed to have a different idea today.

"Miss Snape, please move next to Mr.Malfoy," he said coldly when Eliza shrieked with laughter a few seconds after he walked into the room. When Eliza didn't make any motions of moving, or even indicating that she heard him, he spoke louder and colder, "Miss Snape, I said to move next to Mr.Malfoy!"

"Alright, alright, I'm moving." Eliza threw a despairing look at her best friends and moved to the center table occupied by none other than Chelydrus Malfoy, oldest son of Draco Malfoy. Chelydrus looked like a battering ram had been shoved up his ass; his face was scrunched up in either pain or disdain. Eliza couldn't tell either way.

"You're like your mother was," Snape muttered under his breath, but loud enough for Eliza to hear him.

"What?" she asked, dropping her bag onto the worktable. "Like my mum was?"

"Nothing. Sit down before I take off points for tardiness."

"But I'm here!"

"You're causing the class to be late to start. I advise you to sit down and keep quiet." Snape glared at her for a few moments before turning away and magicking the day's notes onto the blackboard. "Today, we're brewing an Engorgement Potion. I would suggest not spilling, but this class seems to spill no matter what. Now, can someone tell me why I'm telling you dunderheads not to spill?" Eliza's hand shot into the air--over the summer, she had accidently spilled some of her father's personal store of Engorgement Potion onto her hands. Why he had it, she had no idea, but she definitely remembered the reaction of the potion. "Snape."

"Because it causes anything it touches to grow to abnormal proportions. Especially human body parts."

"Correct. Now, you'll find the instructions for making the potion on page 42 of your book. Start working."

The class started to pull out their potion ingredients and measuring out the ones they would need. Eventually, a line starting queuing up for the cabinet where the student stores of potion ingredients were. Eliza rolled her eyes and pulled out the ingredient everyone was certain to be getting -- shriveled fig's root. The girls used it in their love potions and Eliza had no idea why the guys would be out of it. She shrugged it off and continued making her potion. Eventually, when the potion was the deep blue it was supposed to be, she took the cauldron off the fire and signaled towards Jack and Jacob. They quickly went to the antidote cabinet and swiped all of the Shrinking Potion.

Snape noticed that his daughter was sitting at her desk, calm. That wouldn't have been so unusual if it were someone other than Eliza Snape. There were fifteen minutes left in the period and usually, she'd be doing something other than just sitting still. Approaching her table, he slipped his hand to the nape of her neck.

"Professor!" she cried out, indignantly. "What are you doing?!"

Snape raised his eyebrow and moved his hand. "Are you you're feeling alright?" he muttered so that only she could hear him. He was standing over her cauldron on the pretense of examining her potion.

"I'm fine," she muttered back, doing the writing assignment that followed making the potion successfully. "Why?"

"You're not creating trouble." Eliza raised an eyebrow and moved her cauldron back over the fire at the same time Chelydrus was making a subtle move to sabotage her potion. The intense heat caused the engorgement potion to shoot up into Snape's face and cause his nose and lips grow to several times their original size. The potion dripped off his face and down his neck, enlargening his neck right before the stream of potion dropped off his collarbone and down his stomach.

"Professor!" Eliza said, looking up in alarm. She made sure to make it look like Chelydrus caused her potion to shoot up. Fortunately for Eliza, Snape turned in time to see Chelydrus high-fiving his cronies.

"Malfoy. Detention, tonight! Would one of you get the Shrinking potion?!" he yelled.

"Er..Professor, there isn't any Shrinking Potion in here!" Jacob exclaimed, rummaging through the cabinet and sounding convincingly shocked.

"Class dismissed!" he announced. But as Eliza went to leave, he grabbed her shoulder. "Go get your mother. Tell her it's important. And then go to the infirmary and get a vial of Shrinking Potion from Madam Pomfrey."

"Yes sir," she said, before speeding out the room. She took all the shortcuts she knew and headed towards the Arithmancy classroom. She skidded to a halt in front of the door and pushed it open. "Mum! Daddy said it's important!"

"What? Eliza, what's going on?" Hermione asked, looking up from helping one of the seventh years. "This had better be serious."

"Well, Daddy getting Engorgement Potion all over him without an antidote is serious, I thought," Eliza said defensively.

Hermione's eyes widened, and she dismissed the class. Sending Eliza to the Hospital Wing for Madam Pomfrey, Hermione went down to Snape's classroom to see what she could do. When Eliza showed up in the dungeons twenty minutes later, Hermione was speaking in hushed whispers with Severus.

"I've got the Shrinking Potion," she announced, handing it to her mother. As soon as the vial was firmly in Hermione's hand, Eliza darted from the scene and her mother raised an eyebrow.

"Well, now. That wasn't suspicious acting, at all, now was it?" she asked, pouring the Shrinking Potion onto the visible areas of skin. As Hermione moved down his engorged stomach muscles, she cleared her throat. "Er.. We can't really use this past your belly button. The effects are unknown."

Snape glared at her and stalked off into his office.

In the Gryffindor Common Room, Eliza had just climbed through the portrait hole. Jack and Jacob were laughing hysterically, enticing sixth and seventh years to give them odd looks. Sitting up, Jack wiped the tears from his eyes and regarded Eliza.

"So, how's Granddad?" he managed to choke out before laughing hysterically again.

"Fine, I think. I left before Mum could use the Shrinking Potion. No one suspects us, though."

"Thank the gods Malfoy is stupid enough to celebrate right in front of a professor," Jacob said solemnly. "Now, I believe it is time for our mid-morning snack?" he asked seriously, pulling out several muffins and chocolate buscuits from god knows where.

Eliza took a muffin and nibbled on it thoughtfully. "What did you guys do with the actual Shrinking Potion?"

"Well, let's say we got back at some people," Jack said with a smirk. Just then, Thomas and Jerry came thundering down the dormitory stairs, holding up minute wizarding robes. They had just woken up since their first period was free. They saw Jack trying to hide his laughter and immediately went to pin him down.

"Give up the antidote!" Jerry (or Thomas) demanded.

"Never!" Jack gasped through his brother's strangle.

Suddenly, the other twin smiled with glee and pulled his twin off of Jack. "C'mon, mate. We'll just owl Mum. I'm sure she knows how to fix this problem," he said, fully aware of the knowledge it required to restore the robes.

Jack's eyes got huge and Jacob had to hold him down. "Calm down. You know Aunt Ginny'll only send you a Howler about pranks... If you're lucky, it won't come at breakfast. Or the twins would owl home... But DON'T give in." Eliza nodded her support from the low table and then glanced at her watch.

"Hey, we have Defense next... I'm not sure Uncle Sirius is going to like us being late."

Jack leaned into Jacob and muttered, "That's her mum talking, alright. I thought we weaned that out of her LAST year."

"Me too, mate, me too."

"Come *on* already!" Eliza said, impatiently tapping her foot from next to the portrait hole.
