Fortunately, Daan's attention is drawn a bit more to the tadpole than it is with the contents of Astarion's tent. Which means the elf's annoyance and huffiness is met with an exhaustion narrow of his single eye. (Gale had remarked how easy it is to replace it, Daan responded with a flat interesting never considered it shortly before Gale realized it was better to drop the subject temporarily.)

At the suggestion, he holds out the bottle to the cat. There's a pause as the cat tilts his head to look at the bottle, then he hisses at the contents.

"That's about what I thought," Daan murmurs. He looks up at Astarion. "Not a cat fan? You're in good company for that, but if it's any consolation he's here to bother me. Unless you decide to change that."

It's cryptic, but getting into it just sounds exhausting, and why bother getting into any details at all when their time together will be brief? It seems better to just leave the warning as that, and if Astarion doesn't adhere to it then he'll deal with the consequences.
