And here comes in the different ways we can play the game. Depending on our decisions during the game it is possible for Ian and Hana to develop "an understanding". They won´t be big friends, but Ian can score some brownie points with Hana. In the current update we can see a bit of this. So I doubt that the threesome would be unacceptable to Hana on these paths.She will though, having a threesome (with Ian of all people) would be utterly unacceptable for her...I mean...I guess TD could write it that way, but it really wouldn't be believable and it wouldn't fit her character.
