Whoa...PT.2 LOL:D
I saw the SE of PT.1(These are guesses for the next PTs)
3: Knux finds Tails and tries to convince him to stop, they battle, Tails wins, and Sonic finds him.
4:Sonic becomes mad, he becomes Super Sonic yet Tails wins again=( .
5: Tails finds Shadow and battles him, Tails wins thinking he killed Shadow but suddenly he goes mad with power!
6: The dark stranger gets all the emeralds, Tails tries to stop him but fails, then he becomes Super Tails( yet since he's pissed, I think he's going to kill us all :P-fuck!).
7: He fights with him but can't win, Cosmo appears(or at least her ghost) and they beat the stranger together, how romantic!
