Aiwass had left Magnet Hammer's side by the time it was almost dawn.
He didn't even realize the passage of time until Magnet Hammer reminded him with a phrase, "Are you hungry? How about we grab something to eat and drink some more booze."
Magnet Hammer had also drunk until the morning the day before, and only woke up in the afternoon. Now fully awake, he was ready to have breakfast and then go fishing with William.
With no choice, Aiwass could only say "I better go rest a bit" and politely declined on the spot. Then he went upstairs to find Sherlock.
Last night's room arrangements had Jack sleeping in the master bedroom on Magnet Hammer's bed, leaving the room for Sherlock and Aiwass. And Lily went to Hayna's room to sleep with her.
In the end, that was the only way to divide the rooms. Even if Lily could stay with Aiwass, Hayna and Sherlock simply couldn't sleep together.
After returning to the room, Aiwass was surprised to find that Sherlock hadn't slept yet.
