Why do you think Mr. Gold is kissing Cora?!

i think they must've had a romantic past at some point which i'm assuming will be explored at when we meet younger cora which i'm super excited for! :D also i'm thinking since belle has lost her memories since hook caused her to fall through the town lines, i'm thinking gold will be going through conflicting emotions. should he stay with belle and try to find some way to regain her memories or since cora's in town, does he still have feelings for her and think maybe he should go back to her? i'm really excited to find out :)

- To screw with people
- To bother the crap out of Hook lol
- Because he was once Cora's lover and with the loss of Belle (or some other reason) decided to go back to her
- It's really Belle in disguise
- It was part of some deal

Those are just some theories I had.

ever since that episode where Rumple told Regina that he held her once as baby i was like "WHAT?!"
so i really really hope they wouldn't complicate matters it by making him her real dad or something :P

Ok, the bad image flooded back in my head again...
Anyway, I think it's because he's kinda... uh... vulnerable in that moment. Dark One or not, he's still a human in that world, of course magic can heal his every wounds but it can't heal him mentally. Physically, he's fine. Spiritually, he's hurt with the whole trauma. Hook and Cora comes to town, Belle's stuff, Bae's stuff, and then Belle's stuff again. The chipped cup (now a mashed cup) affects much on Rumple, then Cora came to the ~help. Then she offered a kiss, then he thought one kiss wouldn't hurt =_=' and that's how it goes.
