The cold open was cute - acknowledging the various half-arsed ways that the show attempted to hide Melissa's pregnancies. Heh.
I guess they also decided to half-arse keeping job roles straight as well, because I don't think a uniformed sergeant would be assigning cases to detectives. But they have Amy up on their floor all the time anyway, and now Terry's a lieutenant, they should just put Amy back in civvies and have her take Terry's old job.
Bradley Whitford was looking very distinguished. That's a good look for him.
I can't believe we've now met Jake's estranged grandfather and his weird, criminal half-sister, but *still* only met one of Amy's brothers. But at least Amy wasn't relegated to 'supportive spouse' while Jake dealt with his family issues.
Gender reveal parties are terrible, but at least this was just a cake and not people littering or putting themselves in danger just to be the centre of attention. But storylines like this really highlight the limitations of a TV show - where was Jake's mother? Where were all of Amy's family? None of them would miss this, I'd assume. But because they're played by guest actors who may not be available, they're just not present. I kind of wish shows would avoid falling into the trap of exposing the artificiality of their world.
Holt asking Terry if he thinks he's "William Wonka" was very funny. Because of course, the frivolity of playing the flute at work is akin to all that nonsense. They have JK Simmons on the show one episode, then riff on his Whiplash character the next.
The reference to ICE and Hitchcock and Scully being enlightened enough to side with an undocumented immigrant was surprising, and really nice. Amy and Rosa 'punishing' them was a sweet moment.
Also, the baby should have been a girl.
