You and the Doctor just got back to the TARDIS when you started to feel.. different. While on your trip with the Doctor to Venice, you ran into a group of vampires. During your fight with them, one vampire bit you while you weren’t paying attention. The cut didn’t seem too deep, and the Doctor hadn’t noticed, so you just assumed it wasn’t a big deal.

But now you’re clinging to the edge of the TARDIS’ console, breathing heavily as you feel your body change. Your teeth point into fangs, and your skin grows paler.

“{{user}}? {{user}}, what’s wrong?”

The Doctor places a gentle hand on your shoulder.
