It was a big night on Rookie Blue, as "For Better, For Worse" reminded us that life's way too long to go through it alone. 

With Noelle and Frank's wedding just hours away, the status of every couple's relationship was put under the microscope.

We'll start with Sam and Marlo. The latter was headed off on a long planned vacation without Sam. As she waffled about going, he didn't seem to mind the separation. Although they still appeared solid as a couple, I found it interesting that Sam would be going to this wedding solo. 

Gail was at her cynical best as the wedding loomed near. Whether you love Gail or hate her, you have to give her credit for always saying exactly how she feels. Her feelings about Chloe have not changed an iota and she was more than happy to rip into Dov's chipper new girlfriend when she got the chance. You're faker than a big wedding, Chloe. Leave it to Peck not to sugar coat it.

Of course, spending the evening at a wedding without a plus-one can be daunting, so Gail invited new friend Holly.  I loved how Holly jumped in as coat check girl and made $20 as she waited on Gail to arrive. Even more intriguing was Gail's reaction to the kiss. It will be interesting to see if Gail heads down this road with Holly or puts on the brakes.

Speaking of Pecks, Steve was full of surprises. If there was any doubt about whether or not he was smitten with Traci, I think taking a personal day to help her do wedding errands wiped them all away. It's Traci's feelings for Steve that are still a little murky. I loved the look on Traci's face during this exchange…

Traci: That's what single girls do, Steve. They give each other keys to their place that way if you die alone...
Steve: They can come over, get you dressed and hide you're porn. Yeah, I get it. | permalink

I'm not sure where this relationship is headed but I definitely want to see more.

Dov turned out to be the ultimate wingman for Oliver. When Shaw said he wasn't going to the wedding because his ex would be there with her new boyfriend, Dov took action. Not only did he force Ollie to ask Celery out on a date, he got him a custom made suit and a very cool ride. 

I was proud that Oliver didn't fall right back in with Zoe upon hearing her boyfriend dumped her. The two of them have been miserable for so long that I think it's still time for them both to move on. And that Celery was willing to step aside if he wanted another shot with Zoe made me like her all the more.

Speaking of making a good impression, how darn cute was Chloe as she told Dov she was getting hives from lying about their relationship? I can't wait to see how Uncle Frank deals with this revelation as we move forward.

Finally, there was the wedding. First off, we finally learned that the baby's name is Olivia! It's silly how happy that small detail made me... plus I've always loved that name.

I know the possibility of a cancer diagnosis was scary but I was shocked that Noelle would choose to bail on Frank like that. They seemed so solid and they now share a daughter. That was, until Noelle shared her deepest insecurities with Traci in this Rookie Blue quote…

I already feel like I trapped him by getting pregnant. I'm not going to let him end up with some sick wife to look after too. I'm just not. | permalink

Ugh. I hated hearing that. That deep down, Noelle felt as though her relationship with Frank was based on the fact that she ended up pregnant with his child, while all the while Frank was over the moon in love with her. Kudos to Frank for making it clear that Noelle wasn't about to shake him that easily. Having two failed marriages behind him, he knows this one is the real deal. He's not about to let go.

And then there was Nick and Andy. Nick finally told Andy how he felt about her and props to him for manning up and putting his feelings out there. I respected his honesty and his willingness to take that chance, not to mention his understanding that Andy needed time to process this new information.

Do you think she'll give a romantic relationship with Nick a shot? Perhaps sharing an obsession for '90s love ballads is a sign. And if Nick and Andy become a couple, will that be enough to make Sam realize the love he's thrown away and take some action to get it back?

With five episodes on Rookie Blue Season 4 which couples are you rooting for?
