I agree but let me offer a different interpretation. If Rumple is going after Robin to kill him in FTL of the past (as evidenced by the synopsis) and does succeed in killing Robin, one of the Merry Men would want revenge and would have it out for Rumple. So, you’re a Merry Man and you see Rumple’s true love all alone. Because of what happened to you in FTL you’re character has changed (like the rest of the cast) and you take this opportunity to strike. Rumple took your leader and friend and overall good guy (Robin), so you try to seduce his love. It’s within at least the realm of possibility.
This is my theory as well….God I hope Gold beats the crap out of him. 😆
Favorite Moments: Seeing how the curse landed in our world, Mr. Gold standing between Regina and Snow, Mr. Gold telling Regina to give up on revenge, the final scene between Regina and Snow, Mr. Gold and Charming’s pissing contest, Henry’s speech at the well, Mr. Gold paying his respects to Cora, Regina strutting around town after the curse was cast, seeing Regina become bored with like in Storybrooke,Lana Parilla’s performance and Neal bribing Henry with ice cream
Least Favorite Moments: Mr. Gold’s initial refusal to help Snow, Regina arresting Owen’s dad andoverall the lack of focus on other characters in the flashbacks (I wanted to see more of Mr. Gold, MM, Belle and Jefferson).
