According to Kate, who wrote the book, no. Firestar died of his wounds and apparently Dovewing only imagined him walking away from the fight and the bolt of lightning brought her back to reality. But to me, I think... hmm. If you ever saw the first Harry Potter movie, it felt to me like when Harry brought down Quirrel and Voldemort's spirit came out and attacked Harry, almost killing him. I think this was sort of like that. the very last remnants of Tigerstar dealt one final blow to ensure that at least if he went he'd take Firestar with him.Thanks for the compliments, by the way.
