There were a lot of things that had Johnny thinking. Not least of them being how he’d reacted to the stranger, Mary said his name was Lucas, who had wandered into the bar and spent time with her. All they’d done was talk, which was probably what should have happened since he was new, and yet there was that nagging feeling that Johnny couldn’t shake. And the jealousy.
When Jo showed up, he’d finished his work quietly, and scooted out as fast as he could without it looking like he was trying to flee. He didn’t even really know if he should be fleeing. He and Jo were friends. He had no reason to feel like he shouldn’t talk to her. But after speaking with Castiel and revealing himself for what he was, then talking to Dean and getting the Dad Voice and The Speech About Death, he felt like saying anything to the other of the future Winchester parents would bring those facts to light. Which was absurd. Hi couldn’t be read as anything but hi.
He supposed there was also the risk that Harry might pop around and make some absurd declaration about his new favorite couple. Jo was already side-eyeing him more than a little bit, he had a feeling she might have seen a hand holding that was meant to be for Mary only, and finding out that he and Mary were pretending to be married was only going to make that worse. There was also the kiss that he'd planted on her cheek right before he'd taken off, a thing that he'd not even taken two seconds to think about due to the game they'd been playing.
The couch was his current seating choice, but only because it was closest to the door, and Johnny was feeling a bit too broody to walk any further than that. He could have easily gone into the bedroom and shut the door, and he'd have been confident then that Mary would leave him alone until he came back out, but he didn't know if that was what he wanted. At all.
