Okay, [ whatever you say, clarke, it's still magic ] Science powers, then. I've never had blood with science-y powers. So I don't know if it would work.

[ she does, however, wrinkle her nose a little at the idea of clarke taking her own blood. not because she doesn't trust clarke to do it right, but simply because it hasn't been that long since caroline was a living, beating heart human — and she can't fathom the idea of having been steady enough with a needle to hook up a blood draw to her own arm then. she could stack cans and run a pageant no problem, but she'd definitely been on this side of queasy. not now, though.

granted, if caroline the vampire was going to make someone into her personal blood drive... she probably wouldn't bother with bags. ]

We could test it, if you want? Before you make a bunch of them and need to lie down, I mean. It would be pretty obvious if it works or not.
