Since the onset of DMV, I've consistently expressed my dissatisfaction with the undue focus on Colette and her monotonous character arc. While things had started to show signs of improvement, Episode 6 pushed Colette to her most absurd self yet, and somehow "Blindspot" emerges as the funniest episode of the season by a significant margin. It boasts the highest frequency of one-liners, the best exaggerated slapstick humor, an impeccable balance between the cast, and a cohesive narrative flow. I'm as surprised as you are.

Driven to distraction by Noa's open dating of Mary, Colette instead of taking it in stride like a mature adult, becomes obsessively fixated and turns to Ceci for advice, even though Ceci's amateur witchcraft seems like a ridiculous solution. Once Colette sees Ceci's secret office diorama, she should have left the matter alone, but her desperate need for Noa's attention makes her take a drastic step of leaving a picture of him with a red string tied around the neck in the office freezer. This, unfortunately, leads to a misconception that his crazy stalker has followed him from New Zealand. When Colette tries to downplay this angle, she ends up implicating Ceci, leading to even more ridiculous confusion. The irony here is that "Blindspot" also features the most meaningful development in Noa and Colette's relationship yet, including a hint of a genuine connection. However, he has no idea that Colette is lying through her teeth about everything.
I still don't think this relationship has any real potential, and I do wish that DMV would move on from it since there isn't enough substance to carry it throughout the season. But I do appreciate what Episode 6 does with this angle. We're not supposed to be rooting for Colette, I don't think. Initially, I thought we were, and her bumbling was intended to be ridiculous and charming, but she crosses enough lines here that I genuinely think the show is trying to imply she's a bit of a psycho.
In the episode's B-plot, Barb is driven to distraction by some graffiti that keeps appearing on the health and safety posters around the office. Barb thinks the illustrations depict rockets, but everyone else is well aware that they're penises, thus everyone - especially Gregg - suspects that Vic is responsible. For once, though, he's adamant that he isn't, which turns out to be true as the real culprit is a random kid who has been waiting in line and is drawing rockets.
It's a silly subplot, but it works perfectly in terms of Barb's painful naivety and inter-office politics with Gregg and Vic falling out over the accusations (however warranted they might be). It serves as a nice counterpoint to how overblown the Colette stuff is and contains a bunch of very funny one-liners from everyone. The "twist" was also totally unexpected for me, though in retrospect it was teased earlier when the kid showed up and insulted Ceci by claiming she was the second-hottest woman in the office because "Hot Kristen" was in the bathroom (he even called her "Hot Kristen").
Despite its absurd workplace cringe comedy and even more ridiculous than usual antics, "Blindspot" just works on basically every level. So maybe I'll have to adjust my criticism of this show as we go along.
