I really enjoyed this episode. There was a lot of Danny/Flack interaction.
The not-so-good:
1. When Mac and Adam were tracking the "chip" in the lab, the device (I don't know what it's called) showed the address as 5885 Broadway, 35th floor. Isn't the morgue downstairs from the lab? I seem to recall during "Snow Day" that it was (unknown how many floors down).
2. If Jenny Harper wanted to report her boyfriend missing, what was she doing in Homicide? Also, I don't think they let people just wander around precincts. It's not secure.
3. It was unrealistic the way Flack broke the car window with his gun. If that had been for real he would have seriously cut himself.
The good:
1. Everyone was in this episode.
2. Danny and Lindsay worked separately. I don't remember them being in a single scene together.
3. It was funny when Flack cracked his knuckles in the interrogation room. (Although he has never done so before.) I also liked the way Flack got a kick out of telling Vonley the value of the "gym socks". Flack does like to mentally torture perps, doesn't he?
4. Adam talking about "ass-dialing" was hilarious.
5. When Carson said, "The man who owns these gems will be coming back for them in a few days. If I don't have them in my possession, you might be investigating my homicide."
And then Mac replied, "Then we'll work that case equally hard, too."
Loved it, loved it, loved it. Those two were great antagonists.
6. The scene with Danny talking to Flack in the squad room was special. I really like it when the characters' backstories are shown.
Mac recognized Belson because he recalled an ex-con named Belson. Flack confirmed that that Belson (the ex-con) is the same guy Danny rode with. So, maybe Belson commited a crime recently.
I think Mac remembered Belson as an ex-cop, not ex-con.
