That's An Impressive Costume (Lorne)
There were times when Brennan missed home. She liked going to the Royal Diner and for drinks at the Founding Fathers. She knew there were bars and restaurants she could go to here, but she hadn't really done a lot of exploring since she'd been back and she knew that none of the people she knew would be there anyway. She was feeling nostalgic, though, so she donned her trench coat and hit the sidewalks looking for a diner.
Her boots made small thudding noises on the concrete as she wandered along. Finally, she spied a building that looked promising. She pulled the door open and stepped inside and sidled up to the bar. She didn't want to take up a whole table or booth for herself. That was just silly.
She picked up a menu when it was placed in front of her and immediately ordered a chocolate shake. She was perusing the dinner options when she saw a shadow fall over the bar and then a body settle into the bar stool beside her. It was all in her peripheral, so she didn't get a good look, and since she was not all that great with social interactions, she didn't look up and try to make conversation, either.
She just kept studying that menu for something that sounded good.
