Number one with a bullet

First time watching season 5.This was a decent send off for Penhall.I'd always thought he was with the show till the end.Depp should have made a cameo appearance given that Hanson was Penhall's best friend but i guess he had completely moved on at this point.Would have been nice if Hanson and Ioke had also been given a send off episode.It was weird that they just abruptly disappeared with no explanation.
