Well, that's an interesting start to a story that most definitely captures the eader's attention. Given the condition he put himself into before getting hit with Crucio and ?crucio Maximus/, U daresay that, if he survives, the combined effects are going to be unpredictable for anyone. He could be anything from a squib to much more powerful wizard (personally, given how over-extended he was, I'd argue for a long convalesence that ends with him being significantly stronger & more powerful than he was before). It's undoubtedly the kind of thing that only Hermione, of all his friends, could really help him with.
