Sean and Fiona in “Unfinished Business”

Sean

You're not falling for Frank's "father of the bride" shtick, are ya?

Fiona

Nothing to fall for.

Sean

Well, from here, it looks like ya might be.

Fiona

I'm not letting him in. I'm letting him pay. There's a big difference.

Sean

Just don't want you to be disappointed again.

Fiona

[Laughs] Frank has let me down my entire life. This will be no different. I just wanna watch him fake like he's a human for a while. For fun.

Sean

Yeah, fun. Whoo-hoo.

Fiona

Ok, let's make a bet. How long till Frank bails? I give it two days.

Sean

One. If that.

Fiona

If I win, you have to go down on me every night for a week.

Sean

Hmm. And if you lose?

Fiona

Same deal.

Sean

You drive a hard bargain, Gallagher.
