Maybe that was why she was so good at healing and lighting things and teleporting. She wasn't really meant to have things like fireballs or lightning strikes (cool as that would be) and really, Emma would be okay with that. She had a gun and she had her wits, she could make do with that if she needed to.
"This is one thing I'm super good at." And yeah, she might want to show off a little, because she wasn't entirely hopeless, relying on her instincts and just reacting to things. It took little more than a blink and Emma knowing where it was to get the small sugar bowl from the kitchen in her house to appear in her free hand with a smirk.
"I can't light things on fire, but I am fabulous at teleporting objects." If she hadn't learned that, she'd be without shoes, since she routinely teleported them away while she was learning. "That's one I did figure out by myself, well, with a little nudging for necessities, but mostly by myself."
