"I'll do what's necessary," Hank promises. Though until he gets that dose of tranquilizer he doesn't know what will be necessary.

"I think I could still get on the right path. It'd just take me longer, I'd need more people. I'm pretty good at this." Which is why he can get away with not obsessing over saving face. He thinks he could solve it in time.

That is, if he makes it that long. Depends on how many times he can 'win' at Russian Roulette, or whatever other way he tries to destroy himself. It's not as if he has much to live for.

"But I'll not let you hurt anyone if I can help it."
