Though Lisa wanted to make amends with Meredith during the Season 2 reunion, the former friends are still not in a good place at the beginning of Season 3.

Lisa apologized to Seth during Jen’s birthday party for Coach Shah, but he wasn’t willing to forget the things that she said about him, his wife, and his kids.

“I regret all of it,” Lisa told Seth at the birthday party. “Seth, I can’t believe I said those things. I don’t feel that way about Meredith, I don’t feel that way about you. Like, I don’t.”
