I loved basically everything about it (with the teensy exception of that bit at the end where they're teasing the "is Rusty gay?" thing), but in particular:

* Rusty's "I love you"
* Sharon's "as his mother"
* All of Sharon's ridiculously subtle facial expressions
* Provenza's literal D: face when Sharon's upset with him for mentioning option three
* "Can I arrest him, ma'am? He should be arrested."
* Provenza calling her "Sharon"
* The way Sykes and Sanchez take one look at each other and run at the mention of option three
* The look on Tao's face when no one will let him finish describing the sex positions (I vaguely remember a similar scene with him and Brenda yeeeeears ago?)
* Dr. Morales
* THERAPY. ALL THE THERAPY, PLEASE AND THANK YOU
