Castle, Season 5

[being led out of the precinct, Siobhan spots Ryan]

Siobhan:
Fenton?

Ryan:
Siobhan?

Siobhan:
Fenton!

[Siobhan runs up to Ryan and, in front of Jenny, kisses him full on the mouth]

Jenny:
Hey! What the hell are you doing? That's my husband!

Siobhan:
You're married? [slaps Ryan]

Castle:
Whoa, lady, you can't slap a cop.

Siobhan:
You're a cop? [slaps him the other way; patrol cops carry her away]

Castle:
Oh!

Siobhan:
Ugh! You liar! You son of a bitch! How could you? Get off of me! Let go!

[as things settle down, Jenny looks at Ryan]

Ryan:
[awkward pause] I can explain.
