[Ahh, human nature. The bit about the vampires really doesn't surprise him at all, and it's easy enough to guess who those three vampires are. But as embarrassing as the admission is, it does tell Mephisto he should keep an eye on Chuuya's general constitution to make sure he isn't letting himself fall anemic.]

[While it's definitely a strange connection the two of them have now, Mephisto is rather genuine in how he cares for his familiars. It's the reason they remain so loyal to him, even when his personality and mannerisms are hard to tolerate.]

[But while he may be looking at this from an almost clinical point of view, that doesn't mean he's outright incapable of empathy. Loneliness is certainly something a demon like Mephisto understands, even if he too would likely never admit it.]

[With an almost uncharacteristic gentleness, he reaches up to rest a hand against Chuuya's cheek.]

There's nothing wrong with feeling lonely. It's human nature to seek out emotional connections that make you feel comfortable and safe.

But should a time ever come that you cannot find such a connection, I would hope that you remember you're not alone anymore. Even when I am not by your side [His hand trails down, pressing a finger to the little gold tag on his collar that which now binds us means that I am always with you. And should you ever find yourself in times of hardship, you need only call my true name, and I will always be there to listen.

[This would probably sound borderline romantic if he weren't grinning like a supervillain.]
