Charlie's nervous smile broke into a grin as she did the same and laughed, and he scratched the back of his head out of old habit. Usually with girls he started with the witty comments and compliments right away, but for some reason Claire was different. And somehow he knew even if Ana hadn't told him about his relationship with her in the alternate universe, he'd feel the same way.
"Claire." Charlie repeated, pleased that she had introduced herself and not gone running. Her name confirmed it though he had known it already, and his shoulders relaxed a little bit once he realized she didn't think he was a nutter. Just acting like some love struck teenaged boy or something. Which he was very much feeling like at the moment.
At her introduction, he held out his hand to her in an offer to shake it, remembering what his mum had told him about manners a long time ago. "It's nice to meet you, Claire. And the little.." Charlie paused, looking down at the baby for a moment, remembering what Liam used to call him. And his head was shaped a little bit like a turnip- Or at least in Charlie's mind. "Turniphead." he added, cheeks flushing a little bit as he looked back up at her with a grin, "I'm Charlie."
