Coo. Assuming Graf survives long enough to get to Balrog, he may try to awaken Endian. I don't think she's in any state to free herself, but she still has the three Demolition Charges Hibiki gave her at Alt Signia, and would try to self destruct and do damage to Balrog from within. Of course easier said then done, since to do this Graf would need to repossess Endian, which means going chest-to-chest with Balrog so Graf's core is close enough to Endian. Unlike before, Grag brought his core with him this time.

Just food for thought. We both might be dead before this would come to head.
