What Would Carl Sagan Do?

think about it; the show begins with gideon returning to the bau after he’d been on leave due to his ptsd. ptsd caused by a mistake he made resulting in the death of 6 agents in a bombing.

throughout season 1, we see that spencer idolizes gideon. the way in which he idolizes him, however, is complicated. on one hand, spencer sees gideon the same way he sees rossi—pure hero worship. on the other hand, he sees gideon as a more than a mentor, as a father figure. this is less overt than people make it out to be in canon, but it’s true nonetheless.

in the first season, we see gideon mentor reid, with the goal of shaping him into the future of the bau, the best profiler they’d ever had. we also see the similarities between reid and gideon, though subtly, at this point. it’s established that gideon and reid understand each other (perhaps in part as a result of both of them being on the spectrum), in a way that the other members of the team, do not.

in season 2, however, we see gideon start to grapple with the implications and consequences of reid’s job at the bau. this is most clear when reid is kidnapped. at this point in reid’s career, gideon was supposed to protect reid; so naturally, he blames himself for his kidnapping. in “revelations”, when the camera cuts from reid seizing to gideon panicking in the bathroom, he is desperately trying to justify his actions to himself. he blames himself for what happened to reid, and it’s killing him. reid survives, but hardly unscathed, and gideon distances himself, likely, as a result of his own unaddressed guilt. people in fandom criticize gideon for this, but it is realistic. gideon is flawed, that’s what makes him compelling.

the most telling scene, however, is in the episode “jones”. reid finally confesses to gideon that he’s struggling. gideon responds with an ambiguous monologue about knowing the time to quit. when reid declares he’ll never miss another plane again, the look gideon gives him is not one of pride, it’s one of despair. it’s his realization that reid is too far gone, he has decieed to follow in gideons footsteps in the way of giving everything to the job, regardless of what it takes from him.

sarah’s murder was the reason gideon ultimately decided to leave the bau, however, his guilt over spencer’s torture and subsequent addiction undeniably played a role.

the show goes on, gideon leaves and ultimately dies, but both events eventually blend into the background—just another one of reid’s endless traumas. it is not until season 11, especially following morgan’s departure, is when we really start to see a palpable, negative change in reid.

until this point, reid’s character development seems mostly positive. he’s more confident and sure of himself both in the field and as a profiler, and as a person. but with the introduction of diana’s alzheimer’s, we start to see reid become overall sadder, more anxious, and more reserved. gone is his need to prove himself, but we see the beginnings of the toll that the bau has taken, one he is beginning to struggle to justify.

notably, this is especially clear pre prison season 12. emily and jj particularly seem acutely aware of the fact that reid is running himself into the ground at home, while desperately trying to keep everything together at work. then, once reid goes to prison, he never truly recovers.

while the show abandons any meaningful follow up about reid’s ptsd, it’s undeniable that after prison, reid is never the same. unlike some viewers interpretations of this version of reid as being more attractive and confident (more likely stemming from seeing reid as more “masculine”after gaining some weight and keep his facial hair), the signs really point to reid after prison being utterly depressed.

he has anger issues, which clearly distress him, and his heart to heart moments with the team are laced with an underlying desperation, exhaustion, and sadness. in short: reid is drained. the job has taken everything from him in a way he no longer knows how to get back.

the final episode, the show comes full circle, highlighting the parallels between reid and gideon. reid makes a bad call that results in the death of six agents, just as gideon had 15 years prior. if it weren’t obvious enough, reid visits gideons grave in his tbi induced dream sequence. in “jones”, gideon was terrified and guilt ridden over the prospect of spencer turning into him, but it is exactly what happened.
