Okay so yes, there's a good chance the writers screw up the timeline if it's indeed Liam #2 that Colin is referring to, but I still think they'd try to make it work and it can see it happening. It doesn't make complete sense, but this is all I've got xD

So let's see....yeah, Liam /should/ be a child. But children can still be on submarines. (His age due to the curse doesn't matter here because this flashback should be happening before it was enacted) Maybe Liam #2 was separated from Brennan at some point and Nemo picked him up. xD Maybe they will indeed try to squeeze this into the established timeline from when Hook met Regina/Cora up until he was frozen due to the curse. But mainly, I just don't see it being someone that the audience hasn't met yet and Hook's family members that we've met are Brennan, Liam, and Liam #2. And Liam #2 happens to be specifically from his father's side of the family, like Colin was teasing. Would they really introduce us to his estranged uncle or a cousin? I mean, Nemo himself could end up being the connection but idk.
