I'm glad Harry has finally begun to calculate his moves instead of just leaping. As for Snape, I can see your point, but dude, he needs to get over the thing with Harry. Whatever James and the Marauders did to him, Harry had nothing to do with it. Harry has stayed convinced that Snape was evil because Snape acts so damned evil, and it really makes it look like Dumbledore has misplaced his trust. Plus, Dumbledore's comments about his mistakes being bigger because his intelligence is bigger? I think Snape may be the biggest mistake of his life, I think he expected Snape to fake his death, not to actually kill him.
