Having said all I did above, I do agree about Exit Wounds, I think that may just be down to how many relationships Jack was involved in in that ep. Exes, siblings and colleagues. They could have had a few seconds though, I do agree with that.

Not sure about the Ianto death arc thing, it may be the opposite, having developed the relationship, too much potential angst if it were Ianto. Also just being cynical, but Ianto has a massive fan base, they must have realised that. Much as I loved Tosh, and had grown to like Owen, I think they really were the most expendable. The producers seem obsessed with Gwen, even if fans aren't, and also she has too many great characters (Rhys, PC Andy) around her.
