Emmet, Rosalie's partner, remains Emmet. He's always ready for a good fight. The word "fear" doesn't exist in his vocabulary. No wonder he's excited about the fight against the vampire army. During Jasper's instructional lessons, however, it turns out that his brute strength puts him at a disadvantage when faced with a strategic fighter, such as Jasper.
