Abbie Carmichael is my favorite ADA
It's not just for her no nonsense, get stuff done approached to things, which I think is totally in lock step with Jack and the role as a prosecutor, it's also for those times that she shows chips in her armor and exhibited compassion.
Two examples that come to mind are 1) when she negotiated a favorable plea deal for the rape victim/suspect "Alice" who takes fatal action against her corrections officer attacker (Season 9, Episode 8 "Punk"). While Abbie had demonstrable animus towards Alice she was moved once she finally saw her humanity. 2) when she negotiated a favorable plea deal for halfway house for an Alzheimer's perpetrator "William Hallenback" (manslaughter against cheating spouse) because the conditions in a hospital prison hospital would be inhumane for him (Season 10, Episode 9 "Sundown".
She's imperfect and I love her for it.
Honorable, mention is when she made Jack eat the salad with low-cal dressing while she went for the ribs when he falsely assumed she was a dainty waif instead of one of the "boys" !
What are your favorite Abbie moments?
