I'd say the writers never really intended for Liam to have a role. They brought the Nautilus back so that they could explain it's realm-jumping and also have something to carry Hook away and thought "hey, the fans liked Liam, let's give him some screen time too."

Of course, they did kind of lampshade the fact that Hook and Liam didn't get a brother plot - Liam said something about how they never seem to have enough time.
