And again, the thing is that these endings were planned/stated BEFORE Suguha's plot was changed, which is one of the first things I pointed out, the endings were planned back when Part 2 was beginning, and Fujino went through a lot that clearly made him change the plot dude, I've been here from the times of Part 1 so I have seen it all happening live (For example, Suguha very obviously was gonna end up Hebishima's sex slave originally, most likely having threesomes with him and Sinon...and then Fujino put things up to vote and the "get rid of Hebishima" choice came up, thus changing the whole of her plot and her interactions with the main plot).
