1/ Liam looks like Colin

2/ The writers said that we would find out who was his dad ... eventually

3/ I think that almost in every season, when they introduce a new land / realm (and a villian in that land), there are always some connections with the main characters

Ex : Pan is Rumple's father - Zelena is Regina's sister - Ingird is Emma's adopted mother
