“There’s always been some chemistry between Annie and Liam. In the first season finale, he was really flirting with her. Picking on her, yes, but in a flirting way. She was this good girl, but also had this facade on — Liam was determined to break that down.  He was always curious about the real Annie. And I think that’s where it started. Now they’ve bonded over really personal things, so there’s an even deeper emotional connection.”

“But with Liam and Annie, we’ve seen it grow. It grew out of friendship.”
