The Wild, Sweet Mind of Tessa Gray: A Psychological Freefall Through The Infernal Devices

By someone who once thought they were too cool for shadowhunters and now lies awake thinking about Victorian repression and unprocessed grief

Let’s just say it: Tessa Gray is not your average YA protagonist. She is not Katniss-level iconic, she doesn’t throw knives or hack governments, and her tragic backstory isn’t even that original if you squint. But that’s not the point. She’s something rarer—someone whose internality actually feels like a real person’s. And not just a person, but a reader. An observer. A girl so obsessively self-aware she might as well be a sentient Tumblr tag.

Reading The Infernal Devices now, over a decade since Clockwork Angel hit shelves with its corsets and demons and slightly-too-perfect boys, Tessa doesn’t feel outdated. She feels like someone who already knew what kind of story she was in, and still got wrecked by it. And that, honestly, is what makes her psychologically interesting.

Because here’s the thing about Tessa Gray: she is constantly negotiating between personhood and performance, selfhood and script. And yes, okay, we can call this “character psychology,” but what we’re really talking about is a girl who doesn’t know who she is, and keeps trying to read her way out of it.

She’s reading herself into existence

Let’s talk about how many protagonists are just cool, hot girls with a destiny. Tessa isn’t that. She’s not cool. She’s not confident. Her power isn’t even that sexy—like, she shapeshifts, yes, but into other people’s bodies, which is deeply uncanny and weird and identity-erasing in a very Cronenberg-by-way-of-Jane-Austen way. She literally becomes other people. That’s not just metaphor. That’s character construction as physical transformation.

It’s also deeply sad.

Because what kind of girl needs to inhabit someone else to understand herself?

A girl who was lied to her entire life. A girl whose biological identity (not-human, surprise!) was stolen from her. A girl who learned about love and power and morality from books and then tried to apply those rules to a world where people are possessed and everyone’s in love with each other and someone always dies in the end.

Tessa’s psychology isn’t just shaped by trauma—it’s framed by narrative. She is a girl who uses fiction as survival, but the irony is that she keeps trying to live according to plot structures that can’t hold her. She’s trying to be a heroine in a Victorian novel. But this is Cassandra Clare. And this world will absolutely gut you for that.

Everyone loves her—no one knows her

Tessa is loved by basically everyone. Let’s not pretend otherwise. Will, Jem, Jessamine, Charlotte, even the annoying boys at the Institute. This is classic “Chosen Girl” territory—except, again, she doesn’t act like a chosen one. She acts like a girl who's terrified that love is a kind of projection. She doubts people’s feelings, not because she’s arrogant, but because she’s scared they’re not seeing her, just their own idealized reflections.

And honestly? Same.

This makes her psychologically alive in a way that most YA heroines aren’t. She doesn’t default to rage or rebellion. She defaults to doubt. Silence. She internalizes things so hard it almost burns holes through the page.

There's this subtle masochism to the way Tessa moves through relationships—especially with Will and Jem. Not because she’s playing martyr (again, not that girl), but because she’s constantly testing how much of herself she can show before she disappears. Her biggest fear isn’t heartbreak. It’s disintegration. Losing the self she’s barely managed to construct.

Which is why the love triangle doesn’t feel annoying or forced. It feels symbolic. Will is chaos and intellect and danger and fiction. Jem is kindness and clarity and music and stability. Both are parts of Tessa. She doesn’t “choose” between them so much as mirror them. And, spoiler, she loses them both in different ways. Because she can’t stay in one shape forever.

A walking contradiction (and that’s the point)

Let’s get messy.

Tessa’s whole existence is a contradiction. She wants to be strong but polite. She’s curious but cautious. She feels deeply but performs restraint. She judges other women for vanity, then fixates on her own perceived flaws. She romanticizes death but also fights to live. She wants to belong but doesn’t believe she can.

And that contradiction is the psychological core of the books.

Because she isn’t an archetype. She’s conditioned—by her Victorian upbringing, by her brother’s betrayal, by being told she’s human and then not-human and then maybe-magical. She doesn’t get to build herself from the ground up like some fresh dystopian recruit. She has to undo and redo herself, over and over again, inside a society that has zero patience for ambiguous girls.

Victorian repression? Oh, it’s here. And it’s personal. Not just corsets and etiquette, but self-regulation as moral compass. Tessa doesn’t just repress her emotions—she believes that doing so makes her good. Until it doesn’t.

There’s this one moment in Clockwork Prince where she lets herself actually feel her desire for Will, and it’s so raw and unfiltered that she immediately retreats from it, ashamed. Not because it’s taboo. But because desire threatens the narrative order she’s built her life around.

That’s the real danger for her—not demons, but the collapse of the story she thought she was in.

Let’s talk about rage. Or rather: its absence

Where is Tessa’s anger?

That question haunted me during the reread. Because we get grief in spades. Despair. Guilt. But not a lot of rage. Even when she’s betrayed, even when she’s manipulated or lied to or literally used as a vessel, she reacts with pain, not fury.

And maybe that’s psychological realism. Maybe girls like Tessa were taught that rage is ugly, unproductive, dangerous. Maybe she doesn’t even know what it feels like to be angry in a way that doesn’t turn into shame five seconds later.

But I also wonder if this is the thing that breaks her—quietly, off-screen, over years. Because the Tessa we meet in the epilogue, all eternal and elegant and bittersweet, doesn’t feel like a triumphant self-actualized version of the girl from the Institute. She feels like someone who survived everything and had to harden herself into an idea. She feels… post-human.

She feels like a ghost.

And that ghostliness—that distance—is maybe the final evolution of a girl who started out trying to live through other people’s stories. Now she is the story. Immortal, untouchable, alone. Archetype achieved.

Except: do we really want that?

So what’s her psychology, really?

It’s not clinical. Not diagnostic. You can’t stick Tessa on a DSM scale or throw around attachment style jargon like Twitter likes to do when analyzing every woman in fiction. (She’s not anxious-preoccupied, okay? She’s just chronically literature-coded.)

Her psychology is this:
A girl learns to read. A girl believes stories will save her. A girl becomes the kind of person who makes herself small so others can love her better. A girl loves back—hard. A girl shapeshifts to survive. A girl becomes a woman who outlives everyone she ever loved.

It’s messy. It’s poetic. It’s not trauma porn, but it’s not sanitized, either.

Tessa’s mind is not a clean arc. It’s a haunted library. A place where every book is annotated, every mirror cracked slightly, every love story unfinished. And she walks through it, day after day, trying to remember which version of herself lived in which room.

And that, for a YA series full of clockwork monsters and demon-blooded boys, is shockingly tender and true.

Final (non)thoughts

There’s something audacious about writing a character like Tessa Gray in a world that screams for immediacy. She’s slow-burn, internal, layered in ways that don’t pay off until the very end—or don’t pay off at all. She doesn’t give us catharsis. She gives us resonance. Which might be more valuable.

Because when we talk about the “psychology of character,” we’re often trying to name something that doesn’t want to be pinned down. We’re talking about the feeling of recognition. That sudden, quiet, destabilizing moment when you see a thought you’ve never admitted reflected back at you in someone else’s monologue.

Tessa Gray gives us that.

She’s not the girl we want to be. She’s the girl we were—reading under covers, negotiating ourselves into people’s affection, unsure if we were real yet.

And if that’s not a story worth shapeshifting into, I don’t know what is.
