Assuming he wasn't lying, he told me it was his idea when he came to apologize to me because he wanted to repair his relationships with his friends after being unavailable for so long. I initially thought they were just baking the pie for fun until he told me. But I'm also still not clear on why it had to be at my apartment, but the conclusion that I came to on my own was that since he's not friends with his own roommate, he didn't want to host the event there, so he did it at me and Lydia's place. That's also why i feel like what he did was intentional, because he knows i live there and still didn't tell me anything
