Mac is home after his bachelor party.  He has just admitted to Jax (who has now left) that he's in love with Felicia.  At the same time Felicia was at the PCPD admitting to V. that she's in love with Mac.   Felicia is now at Mac's house.

Felicia:  How was the bachelor party?

Mac:  Well, as good as a party can be without any women.  I was going to call you.

Felicia:  What stopped you?

Mac:  I was...

Felicia:  Drunk?

Mac:  Drunk? Me, drunk? No, no, Felicia, I have already combed my teeth and brushed my hair, and I'm fine as long as I'm not vertical.

Mac lies down on the couch.

Felicia:  Better?

Mac:  Getting there.

Felicia:  About those invitations...

Mac:  Yeah?

Felicia:  Well, I could take them home and address them at home, or I could stay here and address them at your kitchen table.  What do you want to do?

Mac:  I don't know, Felicia.  What do you want to do?

Mac is falling asleep on the couch.

Felicia:  You may not be drunk, but you sure are sleepy.

Mac:  Maybe I should take a nap.

Felicia:  Oh, good idea.  Forget about the invitations.  You just close your eyes.

Mac:  What are you, my mother?

Felicia:  It's a dirty job, but somebody's got to do it.

Felicia covers Mac with a blanket, sits down next to him on the couch and kisses him on the cheek.  Mac pulls Felicia towards him and they kiss.

Mac:  Stay.

Felicia:  I don't know, Mac.

Mac:  Just for a little while.

Felicia:  How little while?

Mac:  Only...for...ever?  If that works out we'll take it from there.

Mac closes his eyes, falling asleep again.

Felicia:  You're worse than drunk, you're dreaming.

Mac:  Care to join me?

Felicia:  Take a vitamin C for the hangover.

Felicia leaves.  Mac opens his eyes, fully aware of what had just happened.
