Malicia and Yvraine have two different conversations Omake
Yvraine: So...
Malicia: So what?
Yvraine: What's the whole bloodward thing like?
Malicia: Boring, most of the time.
Yvraine: Wait, really? Nothing exciting at all?
Malicia: Well, occasionally I get to do some prisoner play.
Yvraine: ...Really now? I'd never have thought of that.
Malicia: It's mostly a Drukhari thing. You lot don't have the same taste for it.
Yvraine: And Cain?
Malicia: He's always worried about screwing up, but I guess with the right encouragement... he's actually pretty damn effective.
Yvraine: ...Oh my. I'm actually kind of jealous.
Malicia: Seriously?
Yvraine: You've seen the type of Monkeigh that I have to work with. Never wants to actually do anything unless forced to. Even if yours requires encouragement, at least he's trying.
Malicia: ...I didn't realize that the Primarch was so... limp.
Yvraine: I know, I know, but I really am carrying this entire operation.
Krystabel: My lord! Why didn't you ever tell me you liked prisoner play? We could have arranged something.
Cain: Wait, slow down, what? Where did you hear that?
Krystabel: When you ran into Guilliman and his Eldar friends last month, Malicia had a gossip session with Guilliman's "friend" that was overheard by several of our people and at least one Imperial Propaganda officer.
Cain: ...Oh no...
Krystabel: Don't worry, now that we know about Guilliman's performance issues, we've got plenty of material to work with if he tries kink shaming you.
Cain: *Internal Screaming*
