Harry Potter and the Warder of the Phoenix (смешанная)

Fleur Delacour is NOT having a fun Triwizard Tournament. Hogwarts is a mess. She's losing the second task. What are all these literal children and her SISTER doing UNDERWATER? And...
Her inner Veela has chosen that particular moment to point out her two fated mates. The little boy who has hijacked her tournament and the surliest professor at this ridiculous school, Severus Snape.
Excellent. Perfect. The stuff of dreams. Well, it doesn't matter. It doesn't matter if Harry is a literal baby Savior. It doesn't matter if Snape is a double agent caught between the two most ruthless wizards alive. It doesn't matter that none of them will be ready to be mates for years; Fleur is going to keep them all alive if it kills her, dammit.
Severus Snape wakes to realize he has been obliviated, with only three thoughts in his mind. One, he has a fated mate. Two, they insist that he remains alive. And three, he is compelled be aware of the emotional state of Harry Bloody Potter. And Merlin help him, he'll figure it out. Except...how can he figure out HOW Potter is when he doesn't even know WHERE he is? And if the bratty Savior is actually just a broken child, how is Sev supposed to cope with him?
