It really was fantastic - because for once, Killian wasn't plagued with voices and shadowy figures of past Dark Ones; he didn't see them in his peripherals like he usually did, didn't hear them with their tittering laughs and their oozing words. Perhaps the key was just to be high on magic mushrooms all of the time, even if he knew that wasn't feasible.
Once he had his own tongue back in his own mouth, he started laughing again, just completely and utterly delighted. Everything was clouds and chocolate and Stanley - Killian curled up with him on the grass, twisting his hook so that it came free from the brace because he doubted Stan bled chocolate and he didn't want to accidentally poke him. With the hook.
"I don't remember - anything at all," he said, and thought his joke was hilarious so he snorted a giggle or two and closed his eyes, hand pressed on Stan's chest to feel his heartbeat because it was a very precious thing, and if he didn't check on it it may be gone. The way Milah's had been. Oooooooh.
