I want to see him interact with the X-men....namely Hope and see if theres a reaction and whether something will happen to Korvus or not. I love it when a sh'iar is on teams with X-men (Like Lilandra and Cerise).
BTW, the sword itself taught Korvus how to fight I believe. I think it downloaded all the previous owner's skills into him....kinda like that book with Orson Randall and Ironfist.
Also, I'd like to know how Gambit is holding Korvus down with his foot in that one Legacy preview. He should've easily been tossed like a ragdoll.
