Beckett and Castle in “Deep Cover”

Beckett

I don't know Castle. Maybe your mom's right. I think elopement's a great idea. There's no planning, no lists. All we do is, we just get married.

Castle

Beckett, I promise you, there is a perfect date for our perfect wedding and we will find it. Trust me.

Beckett

I do.

Castle

Oh, wedding humor. Nice.
