Originally, he didn't plan to do anything at all.
Luciel even let the kid go who was talking nonsense even though he knew that if it weren't for them, Nolan would certainly be injured.
Just as Nolan said, he would probably fight the 2 teenagers and try to protect Nash.
He would certainly be injured by them because he was clearly outnumbered and obviously wasn't that strong enough to overwhelm the two teenagers.
And if there's an accident or if Nolan couldn't protect Nash, then Nash will also be injured.
They'll be injured just for the whims of a boy they don't even know about.
Even though Luciel knew about it, he just let the boy go because he didn't want to deal with such trouble.
But he didn't expect that the boy would come back and even bring his unreasonable mother and some bodyguards.
It seemed that both the mother and son were used to being unreasonable and doing whatever they wanted.
