Every sense is still screaming for Daniel to get out before Nick's mood changes to something less favorable, but Iman seems very much intent on staying and getting drunk with him. It. Even if there are blazing klaxons going off in the far corners of his brain, he's not about to just leave anyone alone with this man, especially after that casual, not-very-veiled threat. Nick has quite plainly stated he's capable of what Daniel's afraid of but for unclear reasons lacks the motivation to follow through. It's hazy, but there's no immediate danger - excepting that which comes from Daniel not thinking anything through.

So he sinks back into the stool beside Iman, still glaring, and stays quiet. For once. Which is probably the wisest choice he's made all day.
