[accidental video]
This video records through the bathroom door, showing Draco standing over the running sink with the sleeves of a white shirt rolled up to his elbows, though that hasn't stopped it from getting splattered with what looks like water, mud, and blood. He's favouring his right arm, holding it close to his chest, and once the shirt is unbuttoned has a bit of difficulty getting it off before dropping it onto the floor. He gingerly eases his forearm under the water with a grimace and holds it there for a moment, then opens the cupboard behind the mirror and glares at the contents as if they have offended him by consisting of so little.
The next few minutes are of him laboriously unwinding a roll of bandage and attempting to wrap it around the weakly bleeding wound. He's not very good at it and it doesn't help that he's obviously in a fair bit of pain so the results are messy.
When the camera turns itself off he's sitting down on the toilet hunched over with his forehead almost on his knees.

Dittany. Origanum dictamnus. Crushed fresh or prepared in a paste, can be used to close wounds and prevent scarring. Very difficult to grow, but I'm sure somewhere in this place must have it.
[ooc: Ask for help? Nevar. I don't know who's writing the hp wiki articles, but in my humble opinion Dittany of Crete is most likely to be the dittany referred to in the series, considering its recorded history and (reputed) healing properties. He'll figure out the video is up there eventually.]
