Of course Hook could still be Emma's true love. True loves kiss doesn't work on memory loss. Recall Snow when she took the potion to forget Charming, she punched him. Rumple couldn't give Belle back her memories with TLK either.
On the sneak peak with Rumple I don't think the monkey is Neal. It did sound like Emma had already talked with Neal and for her words maybe even let him down easy. She says "it was hard" " Henry makes it complicated" who else would she be talking about.
