Ethan managed to get the door open, blasting a hole in it with his wand rather than trying to fight against the water pressure and his brow furrowed when he saw that not only was there a student, but Masterson and his dog. "I have an emergency portkey license." He explained, eyeing the soaking towel in the boy's hands. "Grab that and the dog and I'll charm it for you now." He shifted slightly, thoroughly soaked to the bone.

Once the kid and Masterson had a good hold of the towel and the dog, Ethan nodded. "Transferring you up to the owlery, Cari is up there now with the other detentionees." Ethan pointed his wand, tapping the towel. "Portus!" Once again he didn't bother waiting to watch them leave, rather he waded out... one last check of his old common room was necessary...

... Pets needed rescuing too.
