Well, they drag it out for all seven seasons, but in the end, and by "end" I mean LITERALLY the last episode in the series...Josh and Donna get together and it is glorious.

But oh, those seven seasons were intense. They both had different relationships and Donna fucks up really bad and Josh has to fire her...but Donna/Josh is, in fact, canon. \o/

They are seriously like, the only couple in the show that I consistently rooted for through the entire run of the show.
