Excellent story so far. I am interested to know... will Harry's identity be revealed? I wonder why he didn't just tell Dumbledore his story, wouldn't that have let him have more freedom to deal with Snape?

How often did he try to tell Dd in the old world that Snape can't be trusted? Why would this one listen any more than the other? Besides, to what end, it wouldn't free Sirius any faster. DD trusts Snape and not Odysseus, and he certainly wouldn't trust an insane time/demensional traveller, would he? Harry, at this point, doesn't care about the fight with Voldemort since he assumes it will end in its own time with or without his involvement.
