Gundam Wing Episode 06

Relena returns to Earth and sees her mother, refusing to really accept the fact that she was adopted from the Peacecraft family. I think this is the last time we see her mother. Une requests another chance to kill Relena and Treize allows her to go to Relena's school and take her out. Just before they show up, Relena arrives while the school is holding a big party. She hears that Heero is leaving. Heero is seen once again clearing all his records from the school's computer, then packing. Relena walks in, he almost kills her, but can't. The next we see him he's on the dance floor with him and she's telling him that she will be "fighting with him" from now on, which bewilders him.

Quatre is seen wondering about the other gundam pilots, wishing he could meet them. Duo is seen staring at the stars and thinking about Heero.

Une's MS troops show up at the school and begin wrecking havoc, causing Heero to get into Wing and fight them off. He protects Relena from a falling chunk of masonry, then spends the next several minutes wondering why he did. Une decides to attack Relena herself when Treize calls and says he's decided to spare Relena's life because the situation has changed - he didn't anticipate the gundam being there. When he hangs up, we see him in his office. Noin is talking to him on the comm unit, saying Lt. Zechs will be very relieved. Treize says that since Zechs has done so much for him, it's the least he can do for Zechs.
