Okay! If you did that, I'd respect your decision even though you staying behind wouldn't actually save anyone. Even though you'd be doing it to prove a stupid point. Even though it'd be as dumb and as meaninglessly futile as when - as - like what I did back home.

[ Because that was meaningless and it changed nothing and Jack opened the vault anyway, and this time if she can't get out or has to die she needs it to mean something ]

It isn't about loving anyone best, it's about practicality. If we run out of power again, would you rather I sit here and twiddle my thumbs so we can all die together?
