The vial of dark liquid looks wholly unpleasant, and he wrinkles his nose at it. Ciel explains what it is- what is could do for him- and his hand almost twitches towards it. Almost, but not quite.

He opens his mouth to politely decline. Emet-Selch told him not to follow him, said that they couldn't walk the same path, and Hythlodaeus wouldn't wish to make him worry. He'll do as he promised, because it seems right.

Then he hears another voice, and glances over at the newcomer. His tone is not lost on Hythlodaeus, but without knowing what had happened between them he simply assumes they just don't like each other. He offers up a smile, Ciel's offer still on his mind.

"Not to worry friend, it doesn't look nearly appetising enough to ingest." Though he'd certainly considered it for a brief moment. He turns back to Ciel. "I appreciate the offer, truly." Not the offer to drink black goo exactly, but the offer to be close to Emet-Selch once more.

"Alas, I must decline. He would be quite wroth with me I'm sure, and that is the last thing I would want." He does want to find his friend soon, though. He refuses to accept that they must be enemies.
