I'm going to politely disagree with a take that I saw regarding how Buck's past actions are coming into play with the grief him and the 118 are showing, not going to link it here unless the OP wants me to, because I'm really just treating this as an academic discussion!
The core issue that I have with this take is that it reverses the causal logic of Buck’s relationships. The argument claims that everyone responds to Buck with force because he trained them to, as if his supposed “over-the-top” or “manic” behavior demanded harshness. But Buck didn’t create those reactions—he adapted himself around them. From childhood, he learned that vulnerability meant dismissal, that expressing need meant being ignored, and that he had to perform competence or joy to deserve even basic warmth. By the time the 118 meets him, he is already someone who masks distress until he physically can’t anymore. His emotional outbursts are not “the only way he listens.” They’re what happens when a man who has spent decades being punished for asking for care hits a point where he cannot hold it together any longer. To treat those moments as something he engineered is to misunderstand trauma at a fundamental level: he’s not provoking people; he’s breaking because no one ever taught him how to be held.
Calling Buck “manic” misreads what canon is deliberately showing: a deeply neurodivergent man—very heavily coded with ADHD—moving through the world with under-supported emotional regulation, sensory overwhelm, and rejection sensitivity. His rapid shifts, big reactions, overtalking, hyperfocus, impulsive warmth, and catastrophizing are not signs of mania. They’re the internal logic of an ADHD adult masking hard while desperate to stay connected. ADHD does not make someone immune to tone or to being shut down; it makes them more sensitive to emotional dissonance. I'm putting aside the framing of somebody with mania as negative.
When people around him snap or go cold, he doesn’t hear the content—he hears the rejection. Saying that harshness is what “gets through to him” pathologizes neurodivergence and justifies behavior that the show itself frames as harmful, or at minimum misguided. When people speak to Buck gently, clearly, and vulnerably—Eddie on the balcony, Bobby across many seasons, Maddie in season 5—he absorbs every syllable. The canon repeatedly shows that Buck responds best to calm honesty, not force.
The idea that the team’s reactions are a “trauma response to dealing with Buck” attributes their emotional styles to him rather than to their own histories. Hen’s hyperfocus on responsibility, Chim’s panic-avoidance, Bobby’s paternal caution, Eddie’s shutdown instinct—these are their coping patterns.
They existed before Buck and would exist without him. None of their irritability or avoidance arises because Buck “taught them” to respond that way; if anything, Buck’s patterns of masking and deflection make it easy for them to overestimate his stability. They assume he’ll bounce back because he always tries to. They assume if something is wrong, he’ll say so explicitly—even though he struggles to name his interiority until it breaks the surface. It is not that he only listens when shouted at; it’s that no one notices he’s drowning until he’s already slipped under.
The claim that Buck “hasn’t experienced deep loss” is simply untrue and reflects a narrow definition of grief. Loss is not limited to bereavement. Buck has endured decades of emotional neglect, the loss of a secure childhood, the loss of belonging in his family, the dissolution of relationships, the betrayal of feeling like he needs to sue his family of choice, the shattering of identity after lightning strike-induced death, and the ongoing fear of losing the people he loves because he believes they are the only thing keeping him anchored. His grief is internal, private, and masked. It is not loud, and therefore it is easy for the people around him to assume it doesn’t run deep.
But the quiet grief is always the most dangerous kind, because it is the kind that convinces you you’re not allowed to have it.
To argue that shutting Buck down is necessary or beneficial ignores everything canon shows us about how Buck processes emotion. Buck is a character who listens intently when spoken to with clarity and care. He internalizes every gentle word Eddie has ever said to him. He evolves immediately when Bobby expresses faith in him. He grows when Maddie sets boundaries in a compassionate way. The idea that he only “hears” force is projection—someone confusing their preferred communication style with his.
Buck does not need to be controlled to listen; he needs to be understood. And Buck absolutely does let people in—but he does it in the small ways that neurodivergent, trauma-marked adults do: by showing up, by investing deeply, by doing acts of service, by hovering at the edges hoping someone will invite him closer. When those bids for connection are ignored because they’re not the “right” kind of vulnerability, the fault does not lie with him.
Saying Buck “isn’t a victim” denies the very real fact that he is a victim of his history—not a martyr, not helpless, but formed by circumstances he did not choose. Trauma survivors do not become less “victim-like” just because they reach adulthood. You can be a responsible, growing, self-aware thirty-something and still be carrying wounds from a childhood where you were constantly told you were too much, not enough, or the wrong kind of person altogether. Buck’s emotional struggle isn’t immaturity; it’s injury. His healing is a process the show is actively exploring, and framing his pain as something he caused, or something others must harden themselves against, erases the nuance the writers intentionally built.
Finally, yes, these characters love Buck. But loving someone doesn’t mean you always know how to support them, and it certainly doesn’t make your missteps their responsibility. The group struggles with offering him care not because he won’t let them in, but because they’re used to believing he’s fine until he proves otherwise. Because they rely on him. Because it is easier to assume he’ll weather things than to face how deeply he feels everything. And because his neurodivergent signaling is often understated or misread.
None of that makes their affection invalid, but it does make this take’s insistence that their behavior is healthy or justified inaccurate.
One of the most troubling aspects of the original take is the assertion that Buck is “quasi-suicidal” and that the team’s reactions stem from “trauma responses to dealing with suicidal Buck.” That framing fundamentally misrepresents both his behavior and the narrative intent. Buck has never been suicidal as a character arc. He has taken risks, yes—but risk-taking born from emotional dysregulation, ADHD impulsivity, and a lifetime of equating usefulness with worth is not the same as wanting to die. The show is explicit about this distinction: Buck’s so-called “reckless” moments stem from a belief that his value lies in his heroism, not from a death wish. He seeks purpose, not oblivion. To label him suicidal is to flatten the difference between trauma-based maladaptive coping and genuine suicidality. It also stigmatizes neurodivergent emotional expression by treating intensity as pathology.
More importantly, framing Buck’s past behavior as suicidal shifts responsibility away from the people around him by creating a false narrative where they had no choice but to “shut him down” for his own safety. This is not supported by canon. When Buck has acted impulsively—running into danger, making high-stakes choices on instinct—he has done so in the same way every firefighter on the show does. Eddie, Chim, Hen, Bobby—they all leap into danger. They all take risks. The show treats this as part of the job, not as evidence of a singular psychological instability in Buck. The idea that only his risks should be interpreted as suicidal is rooted in a bias the original poster is unconsciously reproducing: the assumption that because Buck is expressive, emotional, and sometimes chaotic, his behavior must be extreme or pathological. In reality, Buck’s biggest emotional crises have been about abandonment, grief, and identity—not self-harm.
The “suicidal Buck” narrative also erases the actual character who has canonically dealt with suicidal ideation: Eddie. Eddie’s arc in season 5 explicitly engages suicidal themes—losing purpose, operating with a detached disregard for his own survival. Buck never experiences anything parallel to Eddie’s “I don't know if I'm ever going to feel normal again.” When Buck dies in season 6, it is not because he chose danger but because he was struck by lightning—a random, external event that underscores how little control he actually has over catastrophe.
Perhaps most crucially, labeling Buck as “borderline suicidal” feeds directly into the argument that the team’s impatience or harshness comes from protective instinct, when in truth it usually comes from emotional avoidance, projection, or misunderstanding. It is a narrative that absolves everyone else from having to examine their communication patterns and places the entire burden of relational dysfunction onto Buck's shoulders. If Buck were truly a danger to himself, the show would depict intervention, concern, safety planning, or at minimum a direct conversation. Instead, what we see are moments where Buck is dismissed, talked over, or misunderstood—hardly the reactions of people who believe they’re dealing with a suicidal friend. The canon does not support this reading because the character is not written that way, though I concede there's an argument to be made for suicidal ideation in the past.
What Buck struggles with is not a desire for death but a fear that he is not wanted, not valued, or not allowed to take up space. That fear leads to overextension, hypervigilance, emotional volatility, and overcompensation—all behaviors extremely common in ADHD adults who grew up emotionally neglected. To turn this into “suicidality” flattens both trauma and neurodivergence into caricature. Buck doesn’t need to be saved from himself; he needs to be seen. He needs his grief named, his needs acknowledged, and his internal world treated with the seriousness it deserves. Calling him suicidal is not analysis. It is misdiagnosis—and it obscures the thing the show is actually doing: telling the story of a man who wants to live so badly that he keeps reinventing himself just to stay connected to the world around him.
Buck’s arc has never been about “learning to hear harsh truths.” It has always been about learning that he is allowed to need things, that he is allowed to grieve, that he is allowed to be held. And the people around him are learning, slowly, sometimes painfully, how to see what he isn’t saying but desperately wants someone to notice.
