Dinah spotted Fred once they were out of the Impala. She'd received the call on the way over to the Clocktower. She didn't know what her friend wanted to ask, but clearly it was something big if she needed to ask in person. Dinah had warned Fred about Sam's presence, and she'd done the same for Sam. The younger Winchester looked uncomfortable at the prospect, but didn't argue. She felt as though perhaps Dean's brother was beating himself up a little too much over the things he'd done without a soul, but that couldn't be helped, she supposed.
After Fred's phone call, the conversation had turned to the bunker. To the resources that might be available there and the things that had been found since the initial discovery. Dinah laughed at something Dean said as they got out of the car.
"I don't care if it does have swords. I like our apartment and we can't just move into an underground bunker." She was teasing, a little bit. He hadn't said that he actually wanted to live there, but she could see the excitement. And she supposed she couldn't blame him all that much, especially since Sam seemed to have moved in there. Dinah wasn't sure about the idea of sharing a living space with her boyfriend's brother, but it sounded like the place was big enough for several people to live there comfortably and if it gave the brothers a chance to spend more time together, well... she wouldn't be entirely opposed to the idea, she supposed.
