Peter returns the kiss with one to Liz's forehead and pulls her closer. It's very nearly fall now and things are starting to feel colder, but when he draws Liz closer to him, it feels warm. Almost uncomfortably so.

But Peter still holds her because he finds some comfort in being close to her, and he thinks maybe she does, too. And no matter what happens in the future, this moment will still exist for the two of them, even if neither one of them remembers it.

When Peter finally dozes off, he dreams of taking Liz home to meet May.
