Tony grinned and shrugged, "what can I say, I have a high metabolism." It actually had to do with his ability. He could use his power to increase his own velocity, which essentially granted him super speed. Being able move that fast had it's toll because not only did it speed up his external capabilities, but also his internal capabilities. It increase his digestion at an alarming rate. Hence why he needed to eat a lot. Tony listened intently to Kat's story. 

Once Hart had plowed through all his food, trying to be as take as possible, he chugged his drink and then say back in his chair. "Well I'm Tony, and you can call me by my first or last name. Let's see, I also like music and I play the guitar. I even brought mine here with me. I play football but I like all sports." Tony paused, he might as well tell her, maybe she was magical too. "Fine I'll tell you only if you tell me your magic too. You wouldn't have asked if you were special. I have an ability called Velocity Manipulation. It's kind of complicated so I'll just show you." Tony grinned mischievously as he increased his speed to inhuman levels. In the blink of an eye he was no longer in his seat but behind Kat's seat. He whispered "boo" in her ear. God, he loved his magic.
