[This is normal, for Ain. He's...got a unique personality, Vash has learned during his time caring for him. He's very...very high maintenance, and also loves attention. Vash wouldn't say either of these things are bad, of course; it kindof comes with having a bird in particular. But to compensate for all of these things (and the fact that Ain has a bit of a sassy mouth on him), Ain is also very fun to be around. He's interesting, and...he doesn't know. Vash always feels this sense of needing to stay close by. To protect him.

You have this face that makes him want to protect you, Ain.

He continues to gently pull the fingers of his good hand through Ain's hair as he talks, because yes, he definitely could make a comment about that cowlick...but he decides not to, instead happier to let Ain ramble on.]

Well...there's not much I can do about it, I'm afraid. I mean, I can't preen my hair like you can with your feathers!

[He could, but it probably wouldn't work the same.]
