If Jack has slipped further into "feral"-ness, how does he get back out of it and back into control? Is there a possibility of him never coming back to himself?
Hah, well anon, let’s just say that Jack doesnt want to go back to that and avoids it whenever he can.
I’m not going to spoil too much, but that sort of scenario already happened (mostly out of an intense self-preservation sort of instinct and insane regeneration) and he wasn’t able to be pulled out of it without outside intervention. Since then he’s had episodes, but nothing near the sort of critical condition he’s already been hit with.
These days, tiring himself out or getting the shit beat out of him is enough to do it. Like Reaper blasting him with shotgun shells point blank. That sorta thing takes a lot out of you, lmao.
