When Kain awoke it was already the next day and he was in his room, unaware of how he even got there.
However, based on the pointed glare coming from Kairos all throughout breakfast, it was safe to assume that it was Kairos who'd protected his beauty sleep and allowed him to get back the room without waking up.
"Ahem! Thanks for carrying me back. But you know, you could have just woken me up…" Kain said awkwardly as Kairos' expression only grew colder.
"No I couldn't!" Kairos expression contorted with immense rage. "I tried every method short of maiming you and you didn't wake up! Did you take some kind of drug?!"
Kain lowered his head awkwardly, but also in confusion. Beast-tamers are usually quite light sleepers, Kain included.
