That's what happens when you repeatedly hitch your wagon to the same horse...or in this case, a broken-down ol' jackass named JFP.
It's a weird situation with GH though. Billy Miller was very, very popular as Billy Abbott on Y&R, and is now about as interesting as a pile of toenail clippings playing Jason Morgan on GH, the role that made Steve Burton so well-known. GH couldn't show Burton the door fast enough in 2012, so I don't think they would invite him to return....but Jason is being written so poorly these days that Burton would not entertain such an invitation, anyway.
