After a season of controversy where fans provided the demand, CBS provided the supply in the form of Jennifer "J.J." Jareau's declaration that she is returning to the BAU team in the Criminal Minds season finale, "Supply & Demand".

While exciting, to be sure, she came back in the last 40 seconds of the episode with one line to Rossi that confirmed she was coming back.

This was also not really a surprise to many of the show's die-hard fans, since it's been rumored for more than a month that A.J. Cook was returning full time. But it is nice to end the season of at least one show with happy news!

I was on pins and needles after the initial meeting where the BAU team members were each informed that they would be given an opportunity to leave.

After watch Monday's Castle season finale, I was not sure if the show had another trick up its sleeve and be sneaking in a death or departure of its own.

Thankfully everything ended up okay, or as okay as things can be.

My favorite addition to this episode was Andi Swan, played by Amy Price-Francis. I really enjoyed her work on The Chicago Code as Dina Wysocki, but that really does pale in comparison to the strong, bold, confident, agent she portrayed this week.

I don't know if we will see Swan again anytime soon but with The Chicago Code not being renewed by Fox, maybe we will get lucky.

While the case that the team worked on this week was mostly enjoyable, I was very disappointed with the big "twist" of Lucy appearing to be a victim and actually being the leader.

We just had an episode of Criminal Minds: Suspect Behavior where they used the same trope. So, I had it nailed in about 30 seconds when Lucy looked at Renee all surprised that she had counted the guards.

Apparently when the apple doesn't fall far from the tree, it also borrows plot devices.

Of course, I do love how much more of Garcia we get to see and interact with on Criminal Minds as opposed to Criminal Minds: Suspect Behavior.

It is great to see her interact with Morgan, who is clearly her rock and homing beacon on the team, helping her stay grounded and finding her way back to safe ground when things go crazy.

We also got to see her with Kevin and they are so cute together. My hat is off to Nicolas Brendon; itís good to see his skills from playing a teenage nerd as Xander have served him well while playing a 30-something nerd as Kevin.
