Tosh is so observant - at least in so far as she's noticed how well matched Ianto and Jack would be as a couple. They're doing well at keeping their relationship secret if she hasn't managed to figure it out yet! It'll be interesting when she DOES find out!

Shame that Owen still hasn't really noticed Tosh though - gone straight from Gwen to Diane!

I lke the way Jack's dealing with Gwen's attentions, calmly reminding her about Rhys and gently encouraging her to take a holiday with her fiance. Just hope she listens to his advice!
