Eureka, Season 4

Deputy Andy:
(Releasing Zane from the jail cell) Sorry for the inconvenience, Mr. Donovan. The evidence was overwhelming.

Zane:
Well, you can relax 'cause I'm not gonna sue you.

Jo:
Well, glad to see the experience hasn't hardened you. Thanks for your help.

Zane Hang on. You're not getting off that easy, Lupo. I'm not stupid. I know something's happened with the five of you, and part of it had to do with us.

Jo:
Zane, let it go. Grant's been cleared and so have you.

Zane:
I'm not talking about Grant. You had my grandmother's engagement ring, Jo. C'mon, tell me what we were to each other.

Jo:
Nothing. I gotta go. (turns to leave)

(Zane grabs Jo and kisses her.)

Zane:
Then why didn't that feel like a first kiss?
