Haha, could you imagine a character getting recast twice? Oh my. I doubt we'll see Regina with another love interest, but if they wanted to pull something really stupid, they could be like, "Robin wasn't the person with the REAL lion tattoo, he just had the same one......"

But yeah, based off of Sean's exit interviews, it doesn't even seem like he'd want to come back - even for flashbacks. If they didn't bother giving Robin good material while he was a main, I can't imagine them writing a flashback that's meaningful enough for Sean to agree to do it after they wrote him off the show.
