I really enjoyed this episode too! It was interesting to see some of McGee's past. A bit random that it was the audit guy who did it, but I loved how they enjoyed arresting him.
Sooooo nice to see Delilah again, it's been ages. I've missed her.
I loved her reactions when Torres spilled about the last time someone broke into their apartment, and then Palmer let spill that there was a mummified body under their bed. Poor McGee.
Glad the twins at least get a mention even if we don't get to see them. Seems like Delilah's mum babysits them a lot, it was lucky they were with her when the intruder was there.
Yeah, I loved the touch of the pic of Tim and Tony!
The actor who played young McGee was very good.
The ending was really sweet. Loved McGee tap-dancing in the autopsy room.
