Both storylines i enjoyed & a great chance to see part off Adam's life away from the Lab, to deal with his father who has Alzheimer's. Never knew Adam had a girlfriend, quite emotional for Adam & Mac helping him through it. Another great episode.
I expected more from the case; it just seemed kind of "been there, done that" story. Not really any surprises with it.
However, Adam's story line was great! Finally we get to see more about him. My heart broke when he talked to his father about the abuse. Also, it's good to see that Adam has a girlfriend. I hope they stick together because Adam really deserves a love-live after 9 seasons.
I liked the storyline with Adam, and dealing with his father who has Alzheimer's, and knowing he had a girlfriend, the kissing with Mac/Christine just no chemistry i do not see how the writers do not see that, its like kissing your sister. But like the storyline of Adam, but Christine could been left out would made it better. Took away from the Adam story.
