If you haven't played this game, STOP READING THIS RIGHT NOW and simply go, 'aaaaaw'.
In celebration of me beating Bioshock with the good ending, here's a disgustingly sweet picture of Jack and his girls (I counted five in the last cutscene). I hope viewing this doesn't give you diabetes. I love this ending to bits. It was such a sweet reward for being a decent human and rescuing the little sisters. -coughjinxyoumonstercough-
Also, I wonder if Fontaine was lying about the vocal chord surgery not being reversible, or if Jackie boy can't speak like a normal person anymore. Considering the bad ending has Jack being like, the splicer boss, I can't imagine him being entirely mute.
