You want episode 18 of last season, Omnivore. That has the unsub's entire relationship with both Morgan and Hotch. Then there's just generic relationship problems that Hotch had with his wife that got him to the point he's in in Faceless, Nameless--she couldn't take how much the job took him away from her, so she walked out on him (coldly, if you ask me--I could have been sympathetic towards her, but they played it wrong).

I read that Roday co-wrote the episode, and it was incredibly generous towards Dule and Gus's character. Go him.

I noticed that in the credits, and then went to imdb and learned that he's at least co-written several previous episodes as well, although I didn't look hard enough to remember which ones those were.

Roday's co-written:

"An Evening with Mr. Yang"
"Tuesday the 17th"
"Black and Tan: A Crime of Fashion"
"American Duos"
"Scary Sherry: Bianca's Toast"

He also directed "Tuesday the 17th" and it looks like he's been producing, as well.

are there any CM eps that deal with the backstory on the agents?

I'm really bad with Psych episode titles, but I seem to recall Scary Sherry being really funny.

If you want Reid backstory, it's like every episode. Okay, that's a bit over the line. But he gets a lot of history shown. His episodes are S4E06 and S4E07 The Instincts (a little) and Memoriam (entirely) as well as some in S2E22 and S3E01 The Fisher King Pt 1 & 2 because his mother is involved. Morgan gets his story told in Profiler Profiled, which is S2E12. Emily has some of her history come home in S4E17, Demonology.

Other than that, it's just mentions. Hotch met his wife in high school, Rossi's had a bunch of wives, JJ grew up in a small town, got an athletic scholarship to college and is afraid of the woods, Reid is afraid of the dark, Garcia used to be a hacker living off the grid. That sort of stuff.

msbelle,

yes, quite a few. they are spread out all over the place.

thanks guys. clearly I just need to start with season 1 and watch everything over to catch all the bits I've missed. I have watched it off and on, just never HAD to record it.

especially how "that's my best friend, isn't he AWESOME?" Shawn was at the funeral when Gus got up to sing.

That was really great. That and that Gus's grudge turned out to be justified.

For whatever reason, my DVR only picked up the last 40 minutes of House, and it was totally fine! I'm not sure if that means I should stop watching it or not.

Good episode, except that Olivia Wilde can't act at all and that seems to make these producers think we want more Foreteen. If I were House, she'd be in the lab testing samples all day every day, as she makes Jennifer Morrison look like Helen Mirren.
