Exactly.He goes his whole life, his traumatic past, the end of the world and the death of his wife, travels to Mexico and loses his sh*t NOW? Makes no sense.
Another thing that really bothered me from earlier in the season
Nick was a serious addict and he just seemingly quit. No withdraws, nothing. He's looked longingly at a couple of pill bottle since then but nothing too serious. Unless he's still got a stash somewhere that we don't know about, how did he quit so effortlessly?
