Another way the fight could end that might not be total shit could be; Erza and Irene have a sword fight that follows the same pattern as Erza's fight with Knightwalker, Irene cannot continue because she runs out of magic due to Larcade's orgasm aoe draining 99% of her power hence her poor performance in the fight so far and Erza is too injured and exhausted.
