Little tidbits of continuity like this, the kind where you’ll only really notice if you’re paying close enough attention, please me so much. One of the ‘original’ members of Killian’s crew from ‘The Crocodile’ is the same man who hands Killian the knife used to kill one of King George’s guards in ‘Murder Most Foul’. What’s more is you can see the crewman playing with a knife in the scene from ‘The Crocodile’. It creates a nice thread between two moments separated by four seasons, that seemingly have no connection at all. It also adds context to the loyalty Killian instills in his crew and adds weight to the fact that he’s a helluva captain that people will follow through good and bad (this man stayed with Killian through his transformation into Captain Hook and the hell that was Neverland).
Note: I have yet to personally notice this crewman in any other scene, but if he pops up again, I’ll add it here for continuity purposes. :)
