SOD and a bunch of other sites report that Sean Kanan is returning to GH soon, in a contract role. Just what that role is...no one knows. And head writer Ron Carlivati isn't even talking, all he tweeted was: "the plot thickens"... TV Guide isn't spilling and neither is SK.. all he'll say is that he's back and thrilled. Sean played AJ Quartermaine from 1993-97. Billy Warlock was the recast. AJ was "killed off" in 2005.
