Bean thinks his character can be seen on the show in flashbacks, reported Aceshowbiz.
"Just to go back to that for a while, it would be such fun to do. It would be great! It would be bizarre, but it would be great! So I guess if they're going to do flashbacks, then yeah!" he said of appearing on the show again.
When told that it is just a theory as for now, he said, "But it's a good theory! And that should happen, shouldn't it?" adding, "I've definitely got some unfinished business that needs to be resolved there."
The upcoming fifth season of 'Game of Thrones' is expected to premiere in spring 2015.
