I think there are some discrepancies...First off, Ozpin never really ran. They basically told him to go, so he did. Seeing his entire history play out again before him, plus having the people he trusted (as far as he could trust at this point) turn against him probably shattered him. The innocent run when they feel they can not have justice or a fair hearing.Oz was manipulative to a point, but only as much as was necessary. It wasn't something he put pride into. For example, he never manipulated team RWBY into anything. They chose to do those things completely on their own--he just kind of bent the rules for them a little. Any good general in a war for the life of mankind would be selective in the amount of intel he released to others--many life times have taught him that, and we got to see a few of them and how they turned out. It is people like Lionheart that made him have to take these methods, or else all would be lost.If Ruby is anything like Summer, then Summer probably chose her own path, believing it was the right thing regardless of the consequences. The thing is--Ozpin has shown that he will not ask of them such tasks without revealing to them the stuff that is essential. He wouldn't have sent them off with zero info--he wants a semblance of informed consent, but has learned that releasing all of it will net him something similar to what happened when he was with Grimm-Salem.I think the bird thing came much sooner, honestly. Probably around the time he recruited them into the inner circle. At the point where Raven left, she wouldn't have let him do something like that. She had already lost all faith. And which chairs are you referring to? Salem's table? That could represent anything, or be for anyone. It could be the person who died trying to kill Summer, or someone else entirely (IE someone from Atlas...)And most likely, Summer seemed to already know a lot about her silver eyes by that time. I wouldn't doubt that this was a big reason why she chose to become a huntress in the first place--Ruby and Summer might be the last of their line, and Summer had planned to train Ruby before her demise. Even Maria had been coached by her own parent, indicating that it is generally taught through generations. And "we've dealt with them before" also seems to indicate that they were referring to Summer in a way, since the only other time we see a hunter of Silver-eyes is some random person doing it as a bounty.If Oz told Summer about Salem's plan, he would have been honest. Salem holds no love or pity for humanity, and it is obvious she either wants to rule with an iron-first or destroy it. But again, if Summer and Ruby are as alike as Raven hinted at, Summer would have taken the task no matter what--probably without much prompting from Oz.Raven was gone by the time Summer went on the mission. While my illustration is wonderfully symbolic, I do not believe that she would visit the grave with the others. She might come on her own, though (which was how I actually imagined it--each paying respects on their own, while simultaneously breaking away from each other). Raven had left for the tribe two years prior, after Yang's birth--that is already confirmed in the show. She obviously still had communication with her brother, Qrow (again, confirmed in the show) but no one else that we know of for certain.I do think that Qrow had a thing for Summer, but I don't think it was returned.The back story is fascinating, and I can't wait to see more--but I imagine it will come in pieces because of how vital it is
