But if, as part of the development of the characters themselves, they become aware of the fact that they aren't, strictly speaking, straight, but are in fact bisexual or some such, it isn't you changing their orientation just by expressing interest. It's been quite some time since Shepard has had any sort of interaction with Kaidan/Ashley, aside from about a minute or so on Horizon. Oddly enough, people can change quite a bit in this regard over the course of a couple of years. People change, and characters develop in ways we don't always anticipate in the first game.
