This will be the last thing I say on the matter, cause if I continued it would only make me see as a hypocrite and wont really do anything to help.

The section I quoted may not directly say what happens and what not. But I pretty much tells me this two things, that have filled the two episodes, don't happen in the manga. Enough spoiler for me.
