“If by feisty you mean somewhat violent, then... oh, probably,” Loki complained and shook his head. “I'm all for hot and feisty women. In fact that is a combination I rather encourage, unless it risks my personal safety. Being punched or clawed rather looses the appeal.”
Perhaps Thor liked the idea of fighting a bunch of women, Loki really didn't. In terms of fight of flight, flight was always the preferred option when possible.
