It was "Friday the 13th" at 15 Division and the day's craziness was having its effects on the Rookie Blue team.

We finally got to see Marlo looking a little out of control as she sat with her therapist. Was she just having an off day or was she on the verge of a manic episode? And that's obviously one of Marlo's concerns: once someone knows that she's bipolar, they'll always be dissecting her behavior for signs of the disorder. I can see how that fear could make it difficult to open up to people, especially Sam.

Sam was having one hell of a day. First, he was positively gleeful when they found Robbie Robertson's body, almost too happy considering the fact that the case revolved around a dead 18-year old. But I get why he was excited. It must be a great feeling to get closure on a cold case and even better to find out that your instincts were right.

I was genuinely shocked that Sam was willing to let Charlie walk and surprised that Traci was willing to follow him down that road. Sam was obviously scared that his friend and mentor was going to kill himself and he certainly didn't want to send the man to prison but the decision to cover up the crime would have haunted Sam just as much as those scenarios. Perhaps more. 

Thinking about Robbie's tragically short life was depressing. The kid got beaten regularly by his father, was hit by a truck while walking home and then got dumped in a ravine where he drown. Ugh.

And every time Charlie insisted that Robbie was dead I wanted to shake him and remind him that he was drunk when he checked Robbie's pulse. When Charlie turned himself in, he was finally doing the right thing but for Robbie it was too little and far too late.

There were plenty of little moments in the Marlo/Sam/Andy/Nick scenario. Sam and Andy's conversation at the food truck was friendly but awkward. It felt like Sam was trying to reconnect with Andy who was having none of it.

Sam: Well if you don't know me I don't know who does.
Andy: Well, maybe your girlfriend. | permalink

Then, Marlo certainly noticed the identical smoothie cups as Sam and Andy walked in.  Yeah, that's the kind of small thing that would cause niggling doubt in the back of her mind.

By episode's end, Sam took notice of how chummy Nick and Andy were and it sent him running to Marlo to unburden himself about his past as he told her…

I don't want to wake up and realize nobody knows me. | permalink

Too bad Marlo couldn't share with the same honesty. Whether Marlo tells Sam about her bipolar disorder or he finds out on his own it will definitely be a game changer for the two of them. The question is, will they survive it?

Speaking of game changers, that's how Dov referred to Chloe as he begged her for a second chance. I was happy she made him squirm for a while. He deserved it.  I thought I was going to hate these two together at the beginning of the season but now I've begun to wonder if Chloe is just what Dov needs to shake things up a bit.

And how funny was it to watch Dov calmly stand there calling for a medic and using hand sanitizer after Trina had vomited on his shoes and passed out. It was as though none of it fazed him in the slightest.

Of course the one thing Dov couldn't seem to wrap his mind around was Celery the witch but Oliver was fascinated as the unique and beautiful woman flirted with him in this Rookie Blue quote…

Oliver: Do you have a spell that would make my hair grow back?
Celery: Your head is perfect the way it is | permalink

I kept waiting for Ollie to ask her out. He really deserves to have a little fun and Celery looked like a girl who would make him smile.

Gail had an interesting day hanging out in the morgue with Holly.  I could see Gail being quite happy down there, away from people. I loved Gail and Holly's interactions and couldn't help but wonder if we'll be seeing more of her this season.

Finally we get to Nick and Andy. Andy had no idea why Gail was giving her the cold shoulder and Nick really didn't want to talk about it. Then just when it looked like he was about to open up, Andy ruined the moment.

I'm not sure what I think about these two. I always thought they had a brother / sister vibe but it's obvious that Nick wants more than that. A romantic relationship between the two of them would definitely shake up Swarek.  Something tells me that by season's end, Andy may have a decision to make between the two men. 

So should Shaw pursue his witch? Do you believe Nick and Andy should give love a try? And will Marlo's secret cause her and Sam to self destruct? What do you believe after the latest Rookie Blue.
