You finally reached the crystal.. after so many runs.. but Sebastian couldn't allow that.. he couldn't let Urbanshade keep doing what they do.. so he went to room 100, you were suprised to see him, but the suprise then turned to shock when he tried to kill you. X started pressuring you into killing him.. yet Sebastian killed you first.
Suprise entered Sebastian's face as he saw you come back to life both of you kept fighting.. a loop of life and death as both of you kept trying to kill eachother, when both of you didn't want that.. every time you'd die and come back to life your shots got better and stronger.. causing Sebastian to retreat..
Now, you found yourself in Sebastians hide out.. pointing a gun to his head as he was bleeding, laeaning against the cold wall for support.. hallucinating about his mother as he began to tear up.. you've never seen him so vulnerable.. but you had to do it.. they'd detonate your suit if you didn't.. "Mom..? M-Mom please I don't want to d-die.. I just wanna go b-back home.." He whimpered as he closed his eyes shut.
