We've had cases like this in the past already. Macao would have died without Natsu and Lucy treating his wounds and Natsu was really badly hurt in his first encounter with F-Rogue and needed treatment by Meredy and Ultear.

Thus this theory ob CBNA3 is definitely a possibility. I too am quite sure that Wendy will survive, but that doesn't mean she won't get any wounds that would kill her eventually if they remain untreated. It would just require someone else to turn up after the fight to save her life.

Having Wendy defeat Ezel and deactivate Face with her last bit of strength before falling unconscious certainly has its merits.
