"Be sure to warn the others again not to carelessly disturb Ciel when he was sleeping or wanted to sleep," Treyton said to Nichole before following Luciel back to their car.
Treyton already knew that Luciel was very grumpy when his sleeping time was disturbed or if it wasn't enough.
He already experienced dodging Luciel's punches and kicks when he was woken up in the morning.
His punches and kicks were all lethal, as he could accurately target the vital points even though he wasn't even awake.
So, he already warned the others not to disturb Luciel when he was sleeping. If they couldn't dodge his attack, then it would be bad for them.
Most of the time Luciel was just lazy and didn't do anything, so he could only see the deeper side of Luciel in his subconscious reactions.
His laziness and chill attitude in normal times were masking the dangerous character he also had.
