When it's dark enough "You Can See the Stars."  Well things got pretty darn dark on the Rookie Blue season 4 finale but it looks like McSwarek fans got a glimpse of the light.

I doubt I was the only one holding my breath throughout parts of this episode. Even though we had a good idea of what was about to happen, it was difficult to watch it unfold. And there were still plenty of unknowns.

Thankfully, Oliver came out of it largely unscathed. In many ways Oliver Shaw is the heart of 15 Division. If they had killed him off I would have been crushed. Instead he has a concussion and a beautiful girlfriend to dote on him. Also, I was glad Celery didn't tell Ollie about Sam. He needed his rest and there was nothing he could do for his friend. That kind of bad news can always wait.

Before half the division left to track down Kevin Ford, I thought Steve and Traci were once again adorable as he strapped her into her bullet proof vest and tried to convince her to be the last in the door.

Steve: Cowardice is highly underrated, Traci. And you would know that since you're the toughest broad I know and that's saying a lot considering I grew up with Gail. | permalink

I really hope these two are a solid couple when we return for season 5.

Dov was on a roller coaster ride at the hospital. At first I was happy he'd told Wes that he and Chloe were dating. It just felt like the right thing to do and led to some very funny Rookie Blue quotes…

Dov: So how does this work? We wait for her to wake up and then we duel? | permalink

Then things got serious and Wes wouldn't allow the doctors to perform life saving surgery. I had to wonder if he would have taken Dov's opinion more seriously if he didn't know about his and Chloe's personal relationship. When Wes shut Dov out of her hospital room my heart just broke for him.

But there were plenty of broken hearts in this season finale.

Marlo damn near made me cry at the end as she looked at the happy picture of her and Sam in her locker. She's lost the man she loved and most likely her career.  I've grown to care about Marlo and I really don't know where she goes from here. 

I ran the gamut of emotions with Sam Swarek. When he decided to go home, as though he were bullet proof, I was ticked off. Why must he always act like the tough guy?

Then he finally told Andy how he felt. That he couldn't spend one more minute in the same space with her and Nick. He hated the situation but he loved her.

Sam: More than anything in the world I want you to be happy, and you are with him. | permalink

And then he had to go and get shot.

That Andy immediately ran to Sam was a shock to almost no one. As much as I like Nick Collins and have enjoyed his relationship with Andy, she and Sam have always had a palpable connection that just won't die.

In the back of the ambulance, when Andy finally tells him, "You are my story, Sam. You."  I think that answered everyone's questions about with whom Andy's future lies.

And Nick proved himself to be a good guy by doing the noble thing and letting her go, even though it broke his heart. Because much like Sam, I think he loves her and wants her to be happy.

So do you think we've seen the last of Andy and Nick? Will season 5 be all about McSwarek? And who else in Rookie Blue coupledom do you want to see stay together in the future. Stay tuned for our last Rookie Blue season 4 round table in the next few days as we all endure the long wait for next summer.
