Hermes' wings fluff like he's just been electrocuted and he jumps away from Achilles like a startled cat, wings flapping with his sudden flustered energy. But then he hears Dusa's voice, and Achilles' explanation and he forces himself to relax, taking a deep breath and alighting back on the ground.

"Guess we shouldn't put too much store by the privacy here, hmm?" Hermes murmurs, picking the apple off the ground and grabbing Achilles' spear from where it rests against the wall, offering it to his lover with a wink. "You look so much more formal with this."

He takes another moment to just pat down Achilles' hair where he'd accidentally pulled it askew, then goes to the door, checking over his shoulder to make sure Achilles has his bearings before opening it up and leaning against the threshold with his usual easy confidence, favoring Dusa with a warm but opaque smile.

"Hello there, my dear gorgon. Very kind of you to bring all this to my quarters."

He's never gotten as familiar with Dusa as Zagreus has--her anxious mannerisms and his very familiar and speedy hellos and goodbyes tend not to mix well--but she's always seemed like a decent sort to him. And she's helpfully the sort who seems far too anxious to accuse him or Achilles of anything, even if she did suspect something untoward.
