so, Harry assumes his only option is to rescue Sirius at the Ministry himself. This is because McGonagall seeked treatment from an attack at St. Mungo's and he (rather foolishly) assumes that Snape doesn't care, and those are the only two members he can talk to at Hogwarts. But what about the members of e order such as Lupin, Tonks Kingsley, or Moody, did Harry think that the other members of the Order wouldn't have noticed Sirius's disappearance, or that he shouldn't bother telling one of them before heading to the Ministry himself? Sirius might've survived if one of the order members went with him or instead of him to the ministry.
