Olivia, Astrid and others in “Unfinished Business”

Olivia

Hey, what the hell's he doing?

Astrid

He thinks it will help him remember where he's heard about the red and green lights.

Olivia

Okay.

Peter

We've got good news. We think we understand how it was that Ben was abducted. Those red and green flashing lights? They put the father into a hypnagogic state.

Olivia

And we think we might've I.D.ed the woman responsible.

Walter

I have it! Christmas, Christmas leading to Christmas carols, one of which is 'Jingle Bells' which lead naturally to 'Dashing Through the Snow', which of course, inevitably leads one to Dash.

Astrid

To dash?

Walter

Dashel Kim... the man who mentioned the lights to me. I'm sure of it.

Olivia

Where is he, Walter? Can we talk to him?

Walter

Well, I guess that would depend on whether he has succeeded in killing himself or not.
