Yeah, Ray Kowalski (played by Callum Keith Rennie, who you may know from...a bunch of other crap) appears in the last 2 seasons (s3-4). He's awesome. :) I mean, I love Ray Vecchio to death as well, but Kowalski... yeah. Plus Callum, so pretty. And there's even more slashy subtext between him and Fraser than RayV and Fraser, imo. ;) Anyway yeah, I'm totally in love with this show right now... it's my new old fandom.
