[Well, that could have gone better. Unfortunately, Anya's still too close for Colin to fire a shot or close into melee without risk of hitting her. Still, it's something. And Colin knows that sometimes things translate perfectly without words. So, in order to keep the vampire's attention off of Anya, and off of Rin, he backs up, and starts to laugh uproariously at the vampire. He points at the vampire's neck, letting out a loud guffaw, and speaks all the while, his tone jovial in what he HOPES the vampire will interpret as being made fun of.]

Help Rin up, I'll keep Fangs' attention on me!

[With that, he starts patting at his shirt in an exaggerated manner, mocking the vampire's own efforts to put out the flames, and he keeps laughing.]

Look at you! You're like a marshmallow that's been pulled off a campfire!

[Maybe the vampire's plight is a little funny.]
