The Killing airs on Sunday, Callum's character remains nameless,
but
this article mentioned him at least:
Sunday's two-hour premiere (9 p.m. EDT) opens with the juxtaposition of Rosie (Katie Findlay) frantically chased through the woods and homicide detective Sarah Linden (Mireille Enos, "Big Love") on a morning jog her last day on the job before moving to Sonoma, Calif., to marry her fiance (Callum Keith Rennie). But those plans get derailed when she's called to a park to investigate a potential murder after a girl's bloodied sweater turns up.
So unless I am mistaken, he is not the bad guy. Right? RIGHT? :D???? There is still no update on IMDb about this - or Alphas for that matter - but if he is the 'fiance in California' I don't think he'll have much screentime with this one. Damn. :\
(LJ fail continues, some of my icons have been eaten. Hmpf.)
