I've been thinking about random scenes from the anime, and I just thought about this one between Ayato and Yui.
The sudden personality switch from Ayato the moment Laito enters the area is very interesting now looking back on it. The moment Yui wakes up, you can see the concern in Ayato's eyes. He warns her about not coming here when it rains. When he noticed that Yui cut her finger, there was no immediate "mmm, what a sweet scent. Let me suck your blood." There was genuine worry, 'your fingers bleeding. What happened?"
However, the moment Laito comes in, he immediately puts on a mask and gets into his usual "hungry sadist" role. It's so much more obvious that it was a forced reaction due to his brother being present.
I can't help but wonder how the scene would've played out if Laito wasn't there. It's clear that Ayato wasn't into drinking her blood at the time either since he literally just walked out midway through.
