I guess the Kana subplot from Michiru's story will be partially or entirely solved in the next episode, because the student council president is seen with flowers in a hospital and i am absolutely sure that those are not meant for Oojima
edit: seeing that Michiru was present when Yuuki was almost ran over , it is possible that she accompanied Yuuki to the hospital. Thus triggering the entire Kana scene.
The other half of the episode will used to finally resolve Chisato's story. (as seen in the previews)
Which leaves us with 2 (or 3 episodes, eventhough if there is a 13th episode it probably not be aired on tv) for the rest of the story.
Assuming that the last episode will focus on the elections , my guess is that episode 11 will be used to further romantically develop the couple like in the game.
I don't think that the anime will be showing us the 3 way debate (which were present in every route) because there is almost no time left.
As for the elections, i actually think that with the current development Yuuki can win this one if he goes for the same plan as in Isara's story.
In Isara's story he only lost by a small margin at the end but let's take into account that Oojima lost many voters mid way because of his pathetic looking campaigning because only he and Isara were left.
But I think that the team probably won't fall apart because of Chisato.
Although i am reluctant to believe that the students of Takafuji are immediately persuaded by this plan without the 2 "pushes" (and one of them were presented during the 3 way debate) that were needed.
edit:
I don't see the point of adding Mifuyu's "confession" in episode 6, seeing that the anime did absolutely nothing with it and i doubt that they can do anything with it now.
