Iris felt tears well into her eyes the very second Hera lifted the hide flap that served as a door and the scent of whatever was inside flowed out like the high tide rushing toward her. There was no getting around it, Hera was going in there and it wouldn't do well to refuse to go in just because her olfactory senses were under attack by an extremely offensive odor. Coughing once as she breathed in the heavy air inside the building, Iris looked around and frowned. If anything stood out in this ragged group more than a sore thumb, it was she and her Queen.
The sheer level of filth on their skin, hair and clothes alone just made Iris' skin crawl. Something that made her worry about reining in her gag reflex if one of them touched her and she got lord knows what was under their fingernails on her skin. Just the idea made her force back a retch.
Somewhere between the second that they entered the building and when Hera asked for a drink where Iris considered asking Hera what she was thinking considering the smell, everyone was staring in their direction. The Rainbow did what she could to look calm, but she wasn't entirely sure these people understood what Hera was asking for, let alone if she wanted to put anything they may actual provide to her lips.
It probably had fecal matter on it... if not in it. Shuddering, she tried to pass her horror off as a chill from the air seeping under her wool and fur.
Knowing it was in her best interests to help convey what they were looking for, and unsure what language these people spoke, Iris did the same thing she did on her early adventures into the bitter north of the Norse lands -gesture. She raised a hand and tipped it slightly up to her lips and up as if spilling a liquid into her mouth. She wasn't even sure they used cups here. Maybe they used horns like the Norse-folk did. Then she looked to Hera and shrugged. Maybe one of their messages would get through, though, neither of them knew how these people treated strangers.
