Guilliman: Where’s Horus?
Alpharius: Doing stuff.
Guilliman: I don’t like the sound of that. Where’s Magnus?
Alpharius: Trying to stop Horus from doing the stuff.
Guilliman: And Lorgar?
Alpharius: Trying to stop Magnus from stopping Horus from doing the stuff.
Guilliman: I see. And what are you doing here, Alpharius?
Alpharius: I’m supposed to stop you from stopping Lorgar from stopping Magnus from stopping Horus from doing the stuff.
