Chakotay/7. Came from nowhere. *barf smiley*
Gwen and Owen on Torchwood wasn't really a romance, IMO. It was just shagging. As wrong as it was (poor Rhys!), I always thought it was more Gwen's way of dealing with all the weirdness of working with Torchwood. Thank God the affair didn't last.
Never bought Benton and Corday on ER.
