Roan blushed bright red and shifted uncomfortably. "I've been good," he said ignoring her comment about how he liked it. "I got back with Liz. She was dating Ari Ortiz and had a moment of clarity that made her realize that he wasn't good for her and her feelings for him were purely physical. She also wanted more than he was ultimately willing to give so she left."
He had no idea that Ari and Allie had a past relationship otherwise he wouldn't have brought it up. He also didn't bring up Liz's realization of who she really was like he hadn't brought up who he really was. He didn't get the feeling that Allie understood that she was a goddess or possibly a queen from Ancient Greece.
