[Barnaby sighs, now cool and calm as ever.] I could list my trail of sources if you'd like to verify them all yourself, though I'm not sure that's a useful application of our time. Be that as it may, I was very thorough.

The results were a product of my own investigation, so I'm happy to take responsibility from here. If it turns out I was mistaken, the consequences won't fall on your shoulders. [He's giving Gen the out, here, for something he's sure he doesn't have the stomach to do, free of consequence. Surely he'll drop his stubbornness for a change and accept a good deal when he sees it...?]
