Frankie was a trusting girl. Too trusting, and her papa often chastised her for it. So, she wouldn't have known if Grey was playing a game or not. In her eyes, he had a bruised soul. Someone had hurt him deeply, and he wore a tough exterior to try and protect the wound. It served to reel her in quite nicely, making her want to help him, comfort him.
The production of the fireball served its purpose. It lightened the mood, and seemed to bring him out of his momentary funk. Amazing what a bit of fire play could do. She had to be careful with it at school though, as there were races here who had severe aversions to fire. But, she felt it was a safe bet he wasn't one of them, considering he was a smoker.
Frankie let him examine the burning orb in her hand, the flames licking at her flesh, but not harming her. "Nope. Kinda tickles actually. At least for me. It's genuine fire though, so don't touch it." After another moment passed, she curled her fingers around the flames, containing them, and tossed the object out into the damp grass. It didn't stand a chance, and soon flickered into nothingness, leaving her and Grey in the dark again.
"My brothers and I have fire fights sometimes... much to my parents' dismay. I can't tell you how many times I've set things on fire in the house by accident. But, we've got a lot of extinguishers... at least two in every room... so, haven't burned the place down yet!" She laughed lightly and reclined back into the wall, bringing her knees up to her chest with a mild shiver. Frankie grabbed the edges of her borrowed jacket and wrapped it tighter around her body. Now that the sun had fully set, it was getting much colder.
"So, Grey... again, awesome name," she added, unable to help it, "What sort of shit do you do for fun?"
