Loki blinked at him, and realized what he was about really only when the water started dumping down on him. A gallon was drenching, and his face had been upturned, so he immediately started and sputtered, choking and trying to pull away, and not doing a good job of gaining any purchase in his confusion.
"Wha-Glurb! - Hey-Glug! Why-arg!" Loki finally settled for just lowering his head and shielding his face from the onslaught. The jug burped out its last liquid, and he coughed, pushing at rivulets and wet hair on his face with his clumsy palms.
"What's the big idea?" he complained at Damian, eyes back to normal as he stared up at him. Wide awake, spluttering and drenched. His eyes darted about the next second, realizing how high up they were. He rolled to his hands and knees, clumsily getting his bare feet underneath him on the roof's apex. "Ohhhh, hey! I don't remember getting here. Please tell me I wasn't on fire."
"You were not on fire, Ikol offered helpfully from the weather vane. Loki ignored him out of habit, not looking to him as he stared down from the roof, one hand still wiping at water when it ran out of his hair and onto his face.
