When it comes to Jack/Ianto people are seeing different things because we're getting mixed signals. It's as simple as that. There is no overall direction for stories or characters. That leaves different writers putting their own spin on it and the actors improvising with what they have.

While plurality of views is always a good thing from fans Torchwood as a series is suffering from not knowing what its own view is. The Jack/Ianto splinter groups are just one manifestation of a lack of a Head Writer.
