So it's 3 or 4 weeks later since the bomb blew up. They are 'working' on the bomb case . .nothing has been resolved - still no clue who is responsible, just pretty sure it wasn't Ted McDonald. They all had time off while the station was being rebuilt. Oliver is still the boss for now ( not sure he's really liking it any more than he did before)

Marlo is definitely pregnant - she dropped her own little bomb and told Sam - sez she's 4 months along and he's not questioning whether it's his..naturally he's in shock. ( I was still hoping maybe she is delusional-and not really pregnant at all, but she seems ok ).

Sam and Andy have been deliriously happy - which is sweet it just never lasts.. (Freakin' Marlo!)

So Sam calls Andy after his Marlo encounter, to tell her the bad news, but Andy is attacked in the apartment while she's on the phone with him. She fights the guy off and he gets away. She's actually in Traci's apartment - so it's not actually her who was the target and they determine he is a serial rapist who has been stalking and attacking women in the neighborhood. Traci is at Steve's - seems like they're trying again to see if they can make things work.

Introduce new detective (Capello) from Sex Crimes.. who takes Traci's statement and makes her feel really uncomfortable about her personal life. The Sex Crimes D tells everyone this can't be announced cuz people will panic, and the guy will move on and start somewhere else and they'll lose their advantage. The team is upset about this direction and they all go out on patrol and warn the women in the neighborhood anyhow. They tried to catch up to the guy, figuring out who his next target is, but end up with the wrong guy.. they figure the rapist probably got wise and has moved on. So Capello calls the commissioner in to discipline the unruly ranks..he's cranky cuz he got dragged away from a nice dinner..

Dov is working with Marlo, they have become good friends, he is still geeking out on the toys they use - he's really seeming to have found his spot though. Otherwise, he's still being a tool.. Chloe has basically left him alone since he made it clear they're done. He even painted over their special wall in his room with White Paint. She looks heartbroken.

She has been hanging with Nick..he's working out like crazy, thinking of joining ETF - she's sad cuz she feels he's like her only friend at the moment and doesn't want him to leave her there alone. She can't even do a proper pull up ( she hasn't changed.. still hilarious even when she's hurting)

Nick runs into Juliette at the station..discovers she's also a cop. She tells him she disappeared cuz she didn't want to date another cop - he's not letting her off the hook. twists her words a bit "Another' cop? How many have you dated?" (Like he should talk..) and she calls him on that same question... which pretty much shuts him up. So basically she is a transfer from Vancouver - they kinda talk and then it's time for Parade. ( I admit, of all the scenarios and explanations for her behavior when she found out he was a cop, I never considered that she might be a cop too - that was a surprise)

Juliette ends up on booking desk and Chloe is stiff from working out with Nick and can barely move..she joins Juiliette there as punishment for being late to work. Chloe basically tells her all about Nick and Dov , Oliver and the various going's on.

Duncan and Nick are paired up.. Nick is kinda over Duncan and his shenanigans.. but he's doing his best to stay civil. Duncan is a bit calmer - but still a bit on the goofy side.

Gail and Chris are partnered up he's supportive of her trying to adopt Sophie. She has to do a video explaining why she should be chosen to adopt - Chris tells her, just be herself.. she's great. She tells him he seems good.. he says yeah, he is feeling good.. and he's dating a married ex coke addict but other than that.. pfft he's just greeeeeeat. ( Gail must be really happy she is off men - they can be so dumb)

Sam hasn't really had a chance to tell Andy what is going on, though he keeps trying....she's been occupied with trying to keep the neighborhood women safe and catching the rapist and they keep getting interrupted - but she knows something is wrong cuz he's been a bit weird..so when he finally does tell her , she panics and has to get away from him. She is crying alone when Traci finds her and asks Traci to drive her home. Traci knows something is wrong, and leaves with Andy to take her home.

So there are a few more surprises at the end.. Yes, Chris's ex-coke addict IS definitely married. ... to another COP - any guesses who?
Also, Juliette is a cop - but she's not just ANY cop - looks like she's actually doing some undercover investigative work on 15 District - I.A. maybe? Not quite sure who she's after yet.. and it doesn't seem like she is enjoying her secret at all (i'm so happy to see Erin in something again I don't care! I wish she wasn't being sneaky but...I guess we will find out more as the season goes on.
