The two oldest vamps that have physically appeared on the show square off against each other in this hypothetical match-up.

For purposes of fairness, Russell is given a small vial of Warlow's blood before the match begins so daytime is not an encumbrance on the fight. Both vampires are fully fed and at 100% strength. They can use all their abilities shown on the series so far. Outside interference is not allowed. 

Sookie's life is the stake of the battle. BFR is off. Fight is to the true death. Who wins?
