1)Actually the nature of the relic and Vs chances of survival are never made clear. There are multiple sources with different answers to the question. Vik: hurry up and solve it. Hellman: Its already too late. Alt: as long as you don't die I can fix it.
Well to be fair Alt is an all, so for her (maybe) half-truths are still truths. What I mean is that if someone tells you that a lethal poison will kill you and another that the lethal poison will cure you, they are both right you knowAlt might just not see what the big deal is if you lose part of yourself/humanity, while Vik is all 'that's very bad!!' .
