The movie isn't quite at a slow point, per se, but Cesar's seen it enough times that he doesn't care.

He looks over and gives L a reassuring smile, clapping a hand to his shoulder easily. Without drinks and bonding and Star Battles, he would feel the stress of an intruder in his living space far more keenly. Now? L is just inside his circle of friendship enough that Cesar wants him to have this experience. Drinks, old movies, chips--friends. L doesn't seem like he ever had that, not in the ways that Cesar did. He can't go back and fix years of solitude for him, but he can give him a late night of too much pop culture and a bang hangover the next morning.

So long as he doesn't start prying at anything painful, there's nothing that can ruin this.
