“They stretched out their minds, and Fitz's consciousness seemed to merge with Sophie's as they moved almost like a dance, sweeping around barriers and sidestepping defenses. When Sophie's excitement bubbled up, Fitz's steadiness slowed her down, saving her from pushing into a trap. And when Fitz grew too impatient, Sophie was there to calm his mind before he rushed the wrong direction.”

—Narration, in Book 4: Neverseen - Page 500-501

Sophitz/Fitzphie is the romantic/friendship pairing between Sophie Elizabeth Foster and Fitzroy Avery Vacker. From holding hands to crying on each others' shoulders, the two are inseparable. Beginning from when they first met in a museum in San Diego in the first book, Sophie has had a crush on him. These feelings often cause her to blush and her heart to flutter when she is around him. The two also hold hands often, for Cognate training moral support, and romance. Throughout the series, Sophie and Fitz have had a unique bond that becomes stronger and stronger, allowing them to become Cognates, as they trust one another. They often share their secrets with one another, building their bond. Sophie and Fitz both find each other attractive, often complimenting one another or sharing banter. They share many romantic moments, often giving gifts for one another. In Lodestar, Sophie bakes Fitz his favorite dessert, ripplefluffs, he smiles “his first real smile in weeks.” They have had some rocky areas in their relationship, a notable example being in Exile when Fitz blames Sophie for his father’s mind being broken, but Fitz later apologizes when he realizes that it was only his grief making him illogical. In Flashback, they bond even more during the Great Fitzphie Sleepover. Later, Fitz and Sophie reveal their feelings for one another when Fitz takes her to Everglen's reception hall and tells her that her name is the only name he’s ever wanted to see on his match list. They are about to kiss but are interrupted by Silveny when she transmits to Sophie that she is having a baby. Sophie later registers for the match, wanting to be on Fitz’s list, but she is told that she is unmatchable. They begin "dating" in Legacy, although they eventually "break up", as Sophie begins to avoid Fitz and shares secrets with her other friends instead of Fitz. They still have very strong feelings for each other, but both decide they aren't ready to be in a romantic relationship yet.

Quotes

'"So that still freaks you out, huh? That might be proof that it still needs to happen." [Fitz's] eyes locked onto hers, refusing to let her look away. And when she swallowed, it was so loud, she was sure the entire world heard it. " Or," he said, " we could skip the talking." And do what?" she asked, hating her voice for cracking. " Any ideas?" He was so close now, she could feel his breath warming her cheeks"' Shannon Messenger, Keeper of the Lost Cities: Lodestar (p. 666)
' ... his most charming smile and adds, "Red is definitely your color."' - (Fitz to Sophie) Shannon Messenger, Keeper of the Lost Cities: Lodestar
"She liked them [the cognate rings] a little too much actually." Lodestar
"The smile he flashed belonged on a movie screen, and Sophie's heart did a weird fluttery thing." Shannon Messenger, Keeper of the Lost Cities
"Her heart did that stupid fluttery thing again and her skin tingled everywhere he touched." Keeper of the Lost Cities
"... clinging to the one memory that could shine a tiny spot of light in this thick inky haze. A pair of beautiful eyes. Fitz's eyes." Keeper of the Lost Cities
"His mind went quiet, and Sophie figured he'd dozed off with the others. But right as her mind started to drift, he added, I'll always be here when you need me." Lodestar (pg. 269)
"But he was also the boy who'd shown up on her class field trip and shown her where she really belonged. The one who'd let her cry on his shoulder when she had to leave her family, and who'd gone out searching for her in the middle of nowhere, just because he'd heard her voice in his head."
"I'll always remember that you found me and brought me to the Lost Cities and showed me where I really belong. And that you came when I called for help and saved me from fading away. And that you left everything behind to go with me when I joined the Black Swan. Need me to keep going? Because I can."
"She studied the relaxed lines of his features. The soft flutter of his long, dark eyelashes. The adorable way his arms cradled Mr. Snuggles against his bandaged chest. I don't know what to do. She hadn't meant to transmit the words, but it felt... good to say them. And it wasn't like he could hear her. He hadn't flinched. His breathing hadn't changed rhythm. So she told him, I really wish you were awake. He let out a snuffly snore, which gave her the courage to ask, What if I just want you to wake up because I'm tired of fighting the echoes all by myself? That wasn't the right question, though. What if I want you to wake up because I miss you?"
"...there's nothing embarrassing about the way he was looking at you, Sophie. That boy is smitten."
“Sophie had just enough strength left to wrap her mind around the gleaming shards and transmit a call for Fitz’s help. He sent a tidal wave of heat, launching everything up, up, up—through softness and sludginess and pain and relief until she was back in her body, shivering in a pair of warm arms that held her close and careful and wouldn’t let her fall. “Shhhh,” Fitz whispered. “You’re back. You’re safe.”
"Whatever happens next, I'm here with you. You know that right?” Fitz whispered. "I do." The best part was she actually believed him.
"I want it to be you." -Fitz, Flashback
"She tried to convince me to get you crush cuffs for a finals gift when you finished Level Three, but I didn't want to pressure you like that." He stepped closer, reaching for her hands and sounding so adorably shy as he told her, "But... if you want some, I'd go get them in a heartbeat." -Fitz Vacker, Flashback
"No pressure. No time limit. You set the pace and I'll just...follow your lead. But I'll always be right here whenever you're ready–– well, not right here, because that'd get a bit creepy. But... you know what I mean, right?"
"Friends was way better than little sister." - Narration (Sophie's thoughts) about Fitz, Keeper of the Lost Cities

Trivia

Fitz was the first person to introduce Sophie to her true identity as an elf.
Fitz had been looking for Sophie since he was six years old, for over 9 years.
Fitz is one of the two people whom Sophie trusts enough to let into her mind (the other one being the elf that created her, Mr. Forkle.)
Fitz's real name (Fitzroy) can be split into two parts, Fitz and Roy. A meaning of Fitz is, "Son of the king" and the meaning of Roy is, "king/seeker of wisdom." Sophie's name means "wisdom," which could mean that Fitz is seeking Sophie.
Fitz says that the words he uses to enter Sophie's mind are "It's me."
