From the preview after Ep 10 (the 7/17 US or 7/18 Canada showing), it looks like Hunter is back in the next episode.
I was sure that the guy Ted had picked up from Marriage Material.com was gonna die. But he didn't.
I thought this was a good episode, though. Finally, some movement on all plot fronts. I thought it rang true that Brian finally professed his love for Justin. I just don't think it rings true for his decision (in the previews) to propose. Live together, sure, profess love, ok, but not marry. Maybe that's just my personal view point coming through, but I'm pretty certain that no explosion or catastrophe could change my life long stance against marriage (for me; I don't care one whit what others do).
