Well, whatever you choose to do with the metaphor, the point is that you're safe, and you didn't get the drugs into your system. You shouldn't have taken Thomas' money (not without asking, anyway, I'm sure he'd give you money if you needed it), but the fact that you're all right is far more important.

As for Joe, I don't think he'll be splattering anything, though I do expect he will be rather freaked out, and with good reason.
