Lucas and Mary
She was interested in him? Lucas was flattered and he felt his ears turn warm. "Thank you, I mean I like you too so yeah after the baby we can...." what was he supposed to say. Have sex? Because that was what was going to happen but he didn't want to say that. "spend some time together. Just let me know."
Mary intrigued him and not just because she was older although that certainly played a part in it. He knew she came from a different time than this one and he wanted to hear more about it.
