One of Liam's lines is a continuity headache. He says that after his father was killed, and before Nemo saved him, he "grew up next to the docks, fending for myself, desperate to make the people who took them pay."

However, Hook and Regina's first meeting in "Queen of Hearts", and the events of "Swan Song", seem to take place shortly before Regina cast the curse, giving Liam no time to grow up next to any docks... Unless he somehow escaped the curse on his own (but Andrew Chambliss said that Nemo took him outside the bounds of the curse's magic).

Even if we were to assume that these events take place earlier in the timeline that we initially thought, they occurred after Regina began her work to cast the dark curse, which began on Snow White's wedding night (as seen in "The Thing..."), and finished when Emma was born while the curse was cast - and as we know, Snow became pregnant on her honeymoon (as seen in "Unforgiven"), indicating that Regina's work to cast the curse took nine months (unless Snow and Charming had an extremely long honeymoon, which is doubtful, since the queen's threats were looming over their kingdom). So "growing up" still won't fit, even if we move things around (the whole thing is making my head spin - lol).

Personally, I would rather view this as a simple mistake on the writers' behalf.
