By the end of the series, we kind of forget about ol Sheriff Graham here. He didn’t last the whole season but he was pretty notable for his short time on the show.
He’s pretty much the only police officer in the town, which is kind of odd since he should get days off. Is everyone on the honor system on those days?
He basically works for Mayor Regina Mills and does her bidding. Some pretty dark stuff and some petty actions against Emma Swan.
In the magical realm, he was a noble huntsman.
But he later works for the Evil Queen and comes pretty close to the murder of Snow White, but he obviously failed at that task as his humanity wouldn’t let him do it.
While Regina used him for “needs”, he eventually falls in love with Emma Swan, whom slowly starts to accept him back. Then he remembers who he was and what the town really is.
And Regina crushes his heart, killing him before he could tell a soul. Whoops!
