"Yeah, Madoka said something about that. I ran into her on the way here." Kyoko reaches for the bag of chips, even though she just ate and is feeling decently full. "We're not from the same 'timeline' though. We figured that out."

He made food with her, joked about violence, and Madoka told him about Walpurgis. But it's still too soon for Kyoko to be willing to tell him much herself. So she's not going to explain what's different, or what matters about that. What about it matters to her.

"But... It probably doesn't say anything good that that witch showed up in two different timelines."

She doesn't know what it would mean. But... The idea of Homura being the only magical girl left to face her, in Madoka's timeline...

Crunch crunch crunch.
