Alt - "You should come with me. I was a netrunner. I understood how to survive. I cannot speak for you. Beyond the black wall dangers lurk. It is no sanctuary. But it's better to be a free spirit shredded than to wither, trapped in a dying body."
Johnny - "don't do it V. You been running from this all along. It will change you. You won't be you anymore."
And, when Johnny jumps, Alt says :
Alt - "You will become a part of me as V's body and former life are restored."
Which is in line with the following lines, and contradicts somewhat the rest :
V. - "You still plan to obliterate Mikoshi. What about everyone locked away there ?"
Alt - "I will free them. Take them with me."
V. - "Cut the crap. You'll gobble them up like so many morsels of code, make them part of you."
Johnny - "As if they could hope for something better. C'mon."
Of these 3 parts, I see only 2 outcomes.
V. is a netrunner in league with Alt or Rache Bartmoss (yeah, right!) and V. as some pretty good chance as a free spirit in the net (meaning, and AI in itself) or V. is not a top notch netrunner (more than likely) and V.'s lifespan just got drastically shortened.
And, merging with Alt is indeed dying.
