uh oh, another theory, if snape were good, why would he save malfoy when harry owned his ass with sectumsempra (i thought it was perfectly fine to do it to malfoy seeing as how he was using and unforgivable) if snape didnt malfoy, snapes unbreakable vow would be broken without him dyin becuase he was not with dumbledore ... i dunno i just confused myself... i guess that would have thrown his spy plans with LV in the sh!tter if he didnt save malfoy... man JKR is good at this
