Diabhall is about to reply to Allumin, perhaps make note that the wine wasn't going to vanish before he could drink it - but then suddenly there's another man stepping up, all buoyant smile and open posture. He nods politely in response to the greeting, but the onus of the actual introduction is not on him.

Raising an eyebrow under the mask, he slides his glance from the stranger back to Allumin again, fixing him with a look that simply reads: 'Go on.'
