A witchlight? [For a short few seconds, the angel looks a little offended. Or it could be surprise. Castiel isn't the best when it comes to expressing what he's feeling. Something had tugged at him during that short battle, and that is distracting him as well. In his world, he is one of the few or the surviving Seraph. While it wasn't his name spoken, the sensation had still been there.]

It is holy light. I'm not sure if we have any of the darker or demonic sorts in here with us. I don't want to hurt anyone. There aren't enough of us to risk it.

[His eyes sweep over Alec, thoughtful but not questioning whatever it is he sees just yet. Instead, he touches two fingertips to a nearby man who sounds to be a little laboured. Not deadly, but probably a sprung or broken rib. The man's breathing evens and begins to grow stronger. It is only when Alec gets closer to him that Castiel gives Alec his full attention. His angelblade remains in hand, not exactly the trusting sort even of his own allies. See what being around the Winchesters did to an angel? Not that he hadn't done worse to them trying to help.]

You're wounded. [Polite, yep, but Cas isn't all that great with being coy or concerned. He's more blunt and to the point. Some angels just aren't good at pretending to be human.]
