I can live with Jack/Ianto/Gwen which makes no sense given my dislike of Jack/Gwen. As much as I'd like to see that side being developed, of everyone bringing something to a group relationship, it's really going along the lines of Gwen loves Jack, but Rhys loves Gwen and Jack loves Gwen but Ianto loves Jack and Jack loves him back and previously on 'As the World Turns'... Gwen's bi too, certainly, so hopefully Replacement-Tosh (because there has to be one), will have some fem-slash-y vibes with her.

I tend to view the Christmas specials like a view most of the novelisations - possibly canon, but able to be ignored if necessary. It's a Christmas special designed to maintain interest during the off-season, so it can never be the awesome that is injected during the regular show. As long as it's not Star Wars Christmas Special bad, I'm content watching it.

I have faith in Moffat. He made Press Gang AND Coupling.
