So I'm extremely late on this one...
Overall I think I would give the episode a C. Honestly, it was downright predictable...and somewhat annoying in terms of how the case was dealt with. Yes, it was nice to see Mac getting more perspective and seeing things more than just black and white, and I did like to see how he brought up Claire in talking to Maris's mother. However, I just can't believe Mac and Stella could allow the real person who committed the crime (the daughter) go free, Mrs. Donovan not be charged with conspiracy to commit murder, or the admitted hitman with the same charge. Yeah, they were showing compassion to Donovan, so maybe I can see that...but still, why was the daughter not charged?
The baby drama was about the same as I expected it to be....Lindsay actually didn't bother me in the scene where she was confessing her fears of being a mother to Stella-I felt that was her best moment, actually. Her behavior to Adam was pretty b*tchy though. Yes, she was in labor, but why not tell him this right away when she saw him, instead of asking for every other member of the team before demanding he drive her to the hospital? Snapping at him then demanding he do her a favor was pretty selfish. It's Adam-I'm sure she wouldn't have had to demand he help her: had she just told him "I need to find Danny, I'm in labor," I'm sure he would have made the effort to help.
The Ghost Bikes were a nice touch to the episode though. I kind of half expected to see a bike for Ruben Sandoval somewhere....but that would be asking too much of continuity wouldnt it?
(and I guess he didn't really die in a traffic accident...just while on a bike, so i guess it doesnt really count).
But yeah. C. Not too much special about this episode....
