Chuck is not the show one watches for its tight plot. There are always puzzling plot points that don’t really hold up to serious scrutiny. That’s not a big deal, however, because Chuck is not a plot-based show but a character-based show. As long as the main characters behave in a way that does not contradict their fundamental nature or a major narrative arc, it’s all good.
This is the reason 3.17 Living Dead is particularly damning as the quintessential retcon episode. It’s not so much because the plot is absurd (see the first two points below) but because it fundamentally contradicts Sarah’s behavior from the first 13 episodes of season 3 and beyond, the very nature of the Sham relationship, basic human psychology, and commits Sarah’s character assassination (see concluding paragraph).
- There is no penthouse. Shaw stays at a hotel in 3.08 Fake Name and, after that, he lies low in Castle due to the Ring wanting him dead or alive;
- If there is a penthouse, it’s swept clean by government agents after Shaw is revealed to be a traitor at the end of 3.13 Other Guy, just like Casey’s apartment in 3.10 Tic Tac., particularly because the elusive penthouse has a CIA safe installed, with content of potential interest to the Ring, which in fact sends Justin Sullivan in this very episode to retrieve it; a government cleanup voids the whole raison d’être of this episode.
- The DC waterfront restaurant receipt contradicts Shaw’s own words to Sarah during the 3.12 American Hero dinner, “I’m sorry we haven’t done this sooner,” which obviously refers to them going on a first public date together since the ensuing conversation is all about them and their new life together, in an obvious reversal of Chuck and Sarah’s first date in 1.01 Intersect;
- Even if Shaw’s apology is about him not taking Sarah to that particular restaurant (!), there is no need to apologize for not doing so sooner, as they had no time to do so since they were busy doing all the other things mentioned by Sarah during the interrogation scene over the course of the roughly two weeks between the end of 3.09 Beard and the beginning 3.12 American Hero, during which, let’s remember, there are obstacles, such as Shaw being in DC (beginning of 3.10 Tic Tac), Sarah being ready to go back to Chuck (3.11 Final Exam stakeout), or mourning Chuck’s loss (end of 3.11 Final Exam), which are situations not really conducive to romantic dates between Shaw and Sarah;
- The earrings contradict basic human psychology, specifically the universally built-in mechanism of mental association, which we see in Sarah’s own behavior on several occasions:
- In 2.04 Cougars, when she doesn’t want to go to her high-school reunion because it’s associated with painful memories;
- In 3.02 Three Words, when she won’t wear Chuck’s mother’s charm bracelet because it’s associated with painful memories;
- in 3.13 Other Guy, when she walks on the Parisian street where she killed Eve and is immediately reminded of the worst moment of her life.
- Similarly, the earrings would remind her of Shaw and his assassination attempt, as shown in her reaction to seeing Shaw in the 3.18 Subway courtroom scene, and she would never wear them;
- In 3.15 Role Models, when Chuck asks Sarah to move in with him, she replies they are not a normal couple and shouldn’t pretend to be one; so, why would she go with Shaw on romantic dates, which are precisely what normal couples do?
- At the beginning of season 4, after being in love with Chuck for three years and in a relationship with him for six months, Sarah freaks out because she thinks Chuck is moving too fast with their relationship. But she doesn’t freak out when Shaw, a virtual stranger, takes her on a slew of romantic dates and buys her 2-carat earrings at Tiffany’s in the span of two weeks? Shaw is moving just at the right pace?
The greatest problem with the interrogation scene, however, is Sarah mentioning she spent March 22nd at Shaw’s elusive penthouse. March 22, 2010 was the date that 3.11 Final Exam aired. If Shaw’s elusive penthouse is in LA, that seems to imply that she’s there between the end of 3.11 Final Exam and the beginning of 3.12 American Hero,1She can’t be there at the beginning of 3.11 Final Exam because Shaw and Sarah are driving straight back to Castle from the airport, as mentioned by Shaw. And the penthouse can’t be in DC because, in 3.17 Living Dead, Chuck, Sarah, Orion, and Justin Sullivan all get to the penthouse quickly, with Chuck and Sarah getting there after their dinner with Ellie and before Ellie can get to her meeting spot in LA with Justin. having a good time with the man who ordered Chuck’s red test, when she’s supposed to be mourning Chuck’s loss and atoning her guilt for her part in encouraging Chuck into the spy life. What woman, let alone the heroine of a story, does something like that? That’s morally appalling behavior that kills her character.
