I really don’t see how the Milah connection can be a mystery anymore to Emma. Milah was brought up in Nasty Habits. Emma knows Neal is Baelfire, Rumple’s son and Hook said in Nasty Habits, that drawing was something his mother (Milah) loved too. How is it still a mystery now?
it’s crazy how far off some fans will think to drive a wedge between Hook and Emma. If it’s not one thing it’s another, to those people all Hook can do is stay evil and die and in their minds he’s had no development over a season and a half.
