Walder Frey Returning to Game of Thrones

In a recent interview with Zap2It, actor David Bradley confirmed that his character, Walder Frey, would be returning to Game of Thrones.  Although he couldn't confirm whether or not it would be in season 6 or not.  

David Bradley told Zap2It:

He will be coming back, but I can't say when, I can't really say because things are in a delicate situation.  I do look forward to it, because I do love playing someone so irredeemable.  I'm afraid he makes me laugh because he's so appalling to there's a kind of dark humor in there somewhere.
