ooc: dean snuck this into Buffy's room this morning. Don't ask me how he passed through Sam AND Buffy without anyone knowing what he was up to. Dean CAN be sneaky. Okay? Shut up.
Left for her in a plain, cheap, white box is a charm bracelet, something quite similar to this. A hunter charm bracelet that Dean's gotten blessed, namely by a priest and by Tara before she disappeared, shut up! since she's a powerful witch from Buffy's world. And it can never hurt, right?
Note: I didn't forget. See? Just had to make sure that I got all the right charms for it.
