You think you're the only one without parents to be shit out of that Forrest? At least yours cared about you, and you had the ability to save your son. One that's still waiting for you back home, not in this damned realm." This was obviously a large waste of time and he had once again exhausted his resources, time, and effort into someone or something that was beyond help.
What happened to wanting to get home? Was he the only one who wanted to get back to his child? He could have sworn the three of them had that one thing in common, in the very least.

"No, fool, I'm too smart to deal with Regina. And certainly know a lost cause when I see one. Do Hook and I have magic? Are we doing something? Stop playing the clipped bird. If you don't want to help or try, just say so, and stop wasting everyone else's time."
