The one I thought it was is the right one, because I found photos from a school trip recently where you can see Sevda in a few photos. I presume it's the one she helped on recently, she's wearing the Guess coat.
But she's moving school again soon anyway so hopefully she has the sense to keep anything identifiable hidden this time around, I only ever looked it up to see their policies on absence and then to see if she was lying about inset days but the video I saw with the school name on the fridge was obviously also accessible to anyone out there with bad intentions.
