In Isolation (смешанная)

Snarry! Post-war story!
In his 8th year at Hogwarts, Harry can acquire an additional qualification. All he has to do for it is to survive 48 hours without magic in the wilderness – of course, under the supervision of a teacher. And as it naturally must happen, it's Snape who is supposed to accompany Harry. But then, during the outing, Snape suddenly becomes very ill. Harry does what he can to help, even though Snape recoils from the closeness.
