By now, Sera has tried on her dress and is really delighted. She asks
Eggman if she is looking good in it. Eggman, who is now wearing a green
tux, confirms this and suggests at the same time that now, since Sonic is
history, they could start to get a bit more intimate. But Sera is not
very pleased at all about the idea to marry the doctor and become the
mother of a dozen crying egg-babies, which she makes clear by grabbing
Eggman by the throat and shaking him like mad (BTW, the song Eggman sings
in Sera's flashforward that shows her in housewife clothing with a bunch
of babies is a japanese lullaby).
She screams that she won't marry the doctor, never ever.
Meanwhile Tails has filled in the president about the whole story, and the
president asks what Eggman would be up to. It's impossible to destroy the
whole planet this way. Knuckles interrupts and says that this would
surely be possible. During his journeys he has visited many continents,
and found out that the Earth of the Sky is held by ice bridges on the
North Pole. Magma flows through these bridges like blood flows through
veins, and if someone destroys those bridges, the magma would flow out
and melt the ice. As a consequence, all the continents would break apart
and be thrown into space, where they would turn into cosmic dust, leaving
only the planet itself...
Everyone is horror-stricken about this revelation, and Tails asks the
president not to tell Sonic anything about this. But the hedgehog has
already overheard it, since he is standing on a high railing behind the
president. He wants to know what they want to withhold from him and why.
Tails tries to apologize, but just at this moment a message arrives that
Metalla is heading for the North Pole. Before the president can react,
the hedgehog has already left at top speed. So he turns to Tails and
Knuckles again and asks them to help Sonic.
Elsewhere Robotnik is also on his way to the pole, and with a screaming
and raging Sera beside him he flies his Egg-O-Matic into a warpgate.
Knuckles and Tails head in the same direction with the repaired Tornado
(Knuckles standing on top of its wings as Sonic usually does). Tails has
finished his work on Eggman's tracking device, which now scans for Sonic's
and Metalla's brainwaves.
Meanwhile Metalla has reached the North Pole and starts to break apart the
ice to free the magma, but the arrival of Sonic stops him. The hedgehog
is angry that he came too late and wonders where his metal twin could be,
until Metalla comes out of the ice right underneath him. Both contrahents
face each other, and Sonic says that this planet would be too small for
two Sonic's, and that they should fight it to the death. Metalla nods,
and both attack.
