History[]
Sometime in the past, Robin Hood humiliated the Sheriff and took the woman he loved, Marian away from him. Later, he meets up with the Dark One, Rumplestiltskin, in the forest. Rumplestiltskin is looking for Robin Hood, and though the Sheriff knows where the man is, he won't give any information. Instead, he proposes Rumplestiltskin allow him to spend a night with his servant, Belle, in exchange for information on the thief's whereabouts. Rumplestiltskin refuses and finds it easier to rip out the Sheriff's tongue as a threat. He tells the Sheriff he'll give it back for information on the thief. Finally, the Sheriff tells him of the deep grudge he holds against the thief, who goes by the name Robin Hood.
After the Curse, his Storybrooke counterpart is Keith, a frequent visitor to The Rabbit Hole bar. One night, he meets a woman, Lacey (Belle becoming amnesiac because a sort launched by The Evil Queen), who is happily playing pool by herself. He assumes she and Mr. Gold (Rumplestiltskin) are no longer together, so he attempts to flirt with her but is quickly turned down.

Keith is ambushed by an alternate Robin Hood.
Later that night, Lacey goes out on a date at the diner with Mr. Gold. She excuses herself to the bathroom to fix her dress but actually goes out to the alley to meet up with Keith. They make out, and Mr. Gold eventually finds them. He angrily pushes Keith off of her thinking she was being forced upon but discovers it was planned. Keith approaches Mr. Gold to apologize stating he did not know they were still a couple, which Mr. Gold bitterly affirms. Mr. Gold has had enough and using magic, he rips out Keith's tongue and hits him with his cane. Lacey is attracted to Mr. Gold's dark side and watches with a mischievous look on her face as he continues to give Keith a continuous brutal beating.
A few years later, in "Murder Most Foul" Keith is ambushed by an alternate version of Robin Hood, who didn't reform himself and tries to kill the Sheriff with one of his arrows on main street before Regina stops her alternate love, saving Keith's life by sending him somewhere safe. Keith tries to assure Robin that he is no longer the man Hood knew in his past. After sending Keith to safety, Regina manages to calm Robin down and continues to help him adjust to Storybrooke.
