How wonderful, Lupega has recovered his memory! Hack is a rather strange man, but he knows what he's doing. It's a shame about those extreme methods, hahaha. I imagine Lupega is very exhausted; he has no desire to drink alcohol ever again. Well, it wasn't by choice, but it can't be pleasant to feel drunk.
I like the part where the companions are happy about each other's improvement. That's solidarity, camaraderie, loyal people, and a very close-knit group. I love it.
