Hopefully not just Tucker's evolution. The others are probably going to develop as well (Grif still being a lazy coward, but he's already been shown becoming more of a hands on and active lazy coward; Simmons becoming more of a leader instead of a leader asskisser). Caboose of course will probably stay the same.

And their all Captain now, so...that's cool.
