Bishop:
[toasting the princes] To the new King of Stormhold. Whichever of you fine young men it might be.

The Princes:
To the new King of Stormhold. [They acknowledge him and drink. The bishop's face contorts and he collapses, dead. They look uncomprehendingly at their cups, and then eye each other suspiciously. Tertius breaks the atmosphere with a laugh, then chokes and dies]

Septimus:

Primus:

Septimus:
No, Primus, I think you'll find that you killed the bishop by drinking from the wrong cup. [Primus looks crestfallen] Oh look, once you've finished wrestling with your conscience, I suggest you return to your chamber. Leave the quest for the stone to me.
