Alle Kunst ist der Freude gewidmet

Pre-war Ephraim would flounce. Female mercenaries are hardly unheard of (Crimson Flash, anyone?).

Post-war Ephraim... well, if we're dealing with EphRoute Ephraim, I don't think he'd take it very well. Actually, given the way he reacts to Lyon's death, he'd quite likely deny that anything that happened. I mean... Ephraim has a magnificent male body that he is used to and is a big factor in his self-image. Being stuffed into a female form that would, just by nature, be smaller and weaker and different, on top of everything else, just wouldn't be a fun experience.

Eirika would handle it better. Much better, IMO.
