Could Rumplestiltskin and the Charmings been any less taken aback to learn that Hook and Cora had made it to Maine?
Emma and Snow (and friends) are under the impression that they made it through the portal, screwing Hook and Cora at their chance of Revenge. So why are they not shocked - SHOCKED - to know they are there.
Belle is all like, 'Hey Rump, some dude with a Hook hand tried to kill me' and he's just like 'Man, not this guy again.'
People, come on.
