Roddy] Yeah, what about the two dead Horses you had me check on?
[River] What dead Horses?
[Jackson] Struan Loy and Kay White.
They used to work here. Not that anyone would’ve noticed.
[River] They’ve been killed?
[Jackson] Yeah.
[River] What, both of them?
[Jackson] Well, if it had only been one of them, I would’ve only said one name, wouldn’t I?
Christ, it’s… it’s like watching plankton think.
[River] Well, they must be connected, right?
Them and Harkness.
[Roddy] Yes.
[Jackson] Maybe. Which is why we need to address the five Fs. Who the fuck? What the fuck? Where the fuck? And why the fuck?
[River] That’s four.
[Jackson] (sighs) Fuck off…..That’s five.
