[flashback:]
Adrian Monk: That was really fun last night. I haven't been caroling since, I don't know, since college, I guess. I have to thank you for that.
Trudy Monk: For what?
Adrian Monk: For making me do it, getting me out of the house.
Trudy Monk: You are welcome.
Adrian Monk: And I have to thank you for that other thing. You know, marrying me. [sees mistletoe] Oh, look! [they kiss]
Trudy Monk: You are welcome. Did you ever hear anything about that woman?
Adrian Monk: What woman?
Trudy Monk: Ah, the midwife, Wendy something. I overheard you talking yesterday.
Adrian Monk: Ah Wendy Stroud, no no, not yet. It's been 3 days, and it looks like she's really missing. I was actually heading down to the clinic now. Talk to her boss. [tastes salad] You forgot the onions.
Trudy Monk: Did I?
Adrian Monk: Are you okay? [off her look] Trudy.
Trudy Monk: You know, it's really hard being married to a detective, I never get to have any secrets. I'm fine, its nothing. Just a little overwhelmed. I've got so much to do. I'm picking up medication for Ambrose. The bills are due. I got two articles to proofread. And just not enough time.
Adrian Monk: Okay. Wait a minute. That's new. [finds present under the tree] It's for me?
Trudy Monk: Adrian, don't open that. I mean, it's a surprise. Promise me, you won't open it till Christmas.
Adrian Monk: Okay, okay. I won't open the digital watch. I'm putting it back.
Trudy Monk: [hugs Monk] I love you.
Adrian Monk: I can't imagine why.
