A case of mistaken "Identity" left two families shattered and the medical examiner's office scrambling for answers.

Body of Proof delivered a devastating twist as two best friends were misidentified at the scene of an accident. The shocking truth led one family to wake from a living nightmare as they found out that the body in the morgue was not their child and sent another family through the torment they thought they'd been lucky enough to avoid.

As much as I didn't like Susie, I didn't pick her as the killer. I was even more surprised that she came after Megan with that syringe. Considering Susie was a big girl and Megan's about 100 punds soaking wet, she was lucky Bud, Peter and Samantha showed up when they did. As feisty as Megan can be, I'm not sure she could have fought Susie off much longer.

That Curtis wouldn't let Megan take the fall for the identity switch wasn't a surprise at all. The big guy's got integrity to spare. As much as I liked him as chief, he was more fun in the lab and I look forward to seeing more of his sense of humor.

Why was Ethan acting like an idiot for most of the episode? Was he really learning Spanish to impress Dani... who doesn't even speak Spanish? I've always found Ethan to be likable and quirky but this time he was nothing but annoying and frequently made me cringe.

And speaking of Dani, I wasn't sure how to read her character as she gave Peter the where are we heading speech. Did she have serious feelings for him or did she just not want to sign a new lease? Either way, I simply don't see this couple lasting long term.

Lacy's story was the shocker of the night. I thought something might be up when she hit the wall with the hammer but I didn't think it was diabetes. 

I really liked this twist all the more as I watched Megan reel with the news. She's a brilliant doctor. Heck, she even diagnosed Bud's wife just from snippets Bud told her at work, yet she missed the fact that her daughter was a diabetic. 

Sometimes it's hard to see what's right in front of you and no one wants to believe their own child is ill, but I think the guilt of missing this diagnosis will eat away at Megan for a while. I'm looking forward to seeing where they take this story.

Are you happy Curtis is back in the lab and Kate is back in control?  Do you like that Megan's new love interest, Aiden seems to be sticking around?  And what did you think of Lacy's diagnosis on this week's Body of Proof?
