What, with omega?
X: I- We are not fighting to enslave anyone! We just want everyone to get along! (or something like that- I cant remember the exact term used.)
*X shoots a charge shot at Omega*
Zero: Omega... After Fighting with another one of myself, I have realized what my battles up until now have been for(for/meant, once again, word escapes me..) My strength is not meant for destruction... It is meant to protect with my friend those he believes in!
*Zero 3 hit combos Omega*
Farewell, My nightmare!
X: Farewell, My destiny!
X/Zero: Final strike!
Something along those Lines
Or do you mean during the seal?
X pretty much tries to come to grips with what the hell Zero is doing, and Zero philosophizes about the battles theyve fought till then.
X: (I cant remember exactly what he says, but its something along the lines of, "after fighting for everyones sakes... In a state like this!")
Zero: X... Ive been thinking... About(not sure- He mentions I think, wondering about the battles up until now. and mentions that "as long as he's around, The Bloodstained history will repeat itself.")
*siren blares and the seal counts down*
X: Stop the sealing right now!
Zero: Its alright X, The seal is already... Half...
*sound of Doors(?) closing*
and it ends.
I think Zan or Hyper has the translation lying around somewhere.
But it was something like that. Sorry I cant be of more help.
