Being that she had been Barry's doctor in a way, she knew he'd probably need another pizza to keep himself going. Even if he did not exercise his speed as much as he had back home, he still possessed an extremely fast metabolism that let him burn through pretty much anything pretty quickly. It was part of being a speedster; you could eat a ton of food and still have room for a hell of a lot more. A definite perk.
"A teacher? Wow. That's cool," Caitlin replied honestly. She never thought of Barry as being a teacher, but she could see it. He was very intelligent, plus he was friendly and kind. She had no doubt that the students here probably adored him. Even if you hated school, she doubted anyone could come up with a reason to hate Barry or dislike him...outside of the bad guys whose asses he'd kicked in the past. "I bet you're good at it. Did you wow them a bit with a little bit of that Flash speed?" She teased lightly.
At the question, the smile on Caitlin's face wavered just a little. Home. She'd been trying to not think so much about home and how she'd left the team following HR's death which was partly her fault too. She didn't do the team any favors by betraying them and joining up with Savitar. Though she had been Killer Frost, Caitlin couldn't shake the guilt from it...from any of the things she'd done as the frosty metahuman. She folded a curled piece of brown hair behind her ear. "I don't know-I don't know how much I should tell you. I don't know what point in the time line you're from. I wouldn't want to-" She broke off. She didn't want to hurt him with anything she was about to say. It was clear he was so happy here and Caitlin didn't want to ruin it...like she'd help ruin a lot of things back home.
