Denise: Just so I'm clear, you told you to use that machine to get back to your universe.
Stuart: Uh, no, not my universe. His universe, which was supposed to be my universe.
Denise: And he was you?
Stuart: Almost. He was the me I was supposed to have been.
Denise: But if you were supposed to have been him, then how could he have existed to tell you that?
Stuart: Fair question. More importantly, you and I are back together.
Denise: What do you mean, "back together"? We were never together.
Stuart: Okay! Yep. I see what your problem is. You're confusing the you and I that you remember with the you and I that I remember. Easy mistake.
Denise: This is insane.
Stuart: [chuckles] Yes, it is. [hesitantly leans in for a hug and gives up] A wonderful story to tell our grandchildren.
