Lucas & OTA
Lucas had been happily vegetarian for a good portion of his life, and while that wasn't a problem ordinarily it had given him a bit of pause as to what he should bring. He'd settled on an eggplant lasagna -- giving himself flashbacks to when he'd nearly died after Rachel had ended up using infected food in a lasagna she'd made -- because it was something he knew how to make.
Maybe not the most interesting thing, no, but it was his contribution anyway.
After setting the dish down, he snagged a plate for himself and started seeing what else people had brought -- and there was a lot. Decisions were hard, though, especially when it came to food. That meant Lucas quickly decided on the "small portions of a bunch of different things" method.
