Talk about a very bad day. Carla Dalton's couldn't have gone worse. On the verge of finding her nephew after a 12-year investigation, she ended up getting punched in the nose by an bad tempered hockey mom... and then she had her throat slashed with a skate hook.  

"Cold as Ice" was the perfect way to describe her killer.

At first I questioned why we needed to see quite so much blood during the murder scene, but then it made more sense as we watched Frost grow queasy over the body. That's got to be quite a detriment for a homicide detective. 

It was great to watch Frankie step up and out of his sister's shadow as he worked the scene. Sometimes it's hard to see him as anything beside Jane's little brother. 

My favorite moment of the night was Jane trying to stop the hockey game and the referee blowing her off and calling her Mom even after he saw the badge. The expression on her face as she spouted this Rizzoli & Isles quote was priceless…

Even better was watching Korsak's amused expression as she told off the ref. He was more than happy to stand back and watch Jane tear the guy apart. 

The saddest part of the show was Angela's dilemma. She never officially divorced her husband and now his tax problems have become hers - to the tune of $27,000. There's no way Angela's going to be able to raise that kind of money on her own and although it's sweet that she doesn't want her kids to think any worse of their father, they're grown ups and can handle the truth. They should also be given the choice to help out their mom if they can.

Even sweeter was Korsak's offer to loan her the money. He really has turned out to be quite a stand up guy over the years. 

I certainly wasn't surprised to hear that Hope left for Europe. She seems to have a habit of departing town when things get rough. I know Paddy's trial was difficult, but you'd think she'd want to stick around and spend time with the daughter she's just getting to know not to mention the one who just got a new kidney. 

Maura turned out to be a lot more like her biological mother than she ever anticipated as she completely smothered Cailin. I couldn't believe it when Maura called the girl selfish and irresponsible for staying late at the library to study. 

Yes, Cailin was a typical teenager when she invited her friends over without asking, made a mess in the kitchen or played her music too loud but in return Maura completely overreacted. It will be interesting to see if Cailin sticks around for the rest of Rizzoli & Isles Season 4 and how well the two sisters learn to get along. 

Should Cailin become a permanent resident of Boston? Do you care if Hope comes back? And should Angela let her family know she's in financial crisis or should she keep it to herself?
