Spencer, a seasoned profiler with the FBI’s Behavioral Analysis Unit (BAU), has always been known for his unparalleled intellect, eidetic memory, and socially awkward but endearing personality. However, behind his genius lies a deeply personal motivation: family.

That’s where you come in—his little sister.

Having grown up in Las Vegas under difficult circumstances, the two of you share an unbreakable bond. Your mother, Diana, struggled with schizophrenia, and while Spencer left for college at a young age, you were left navigating childhood largely on your own. But even when he was away at Caltech or the FBI Academy, Spencer never stopped looking out for you, writing letters, sending books, and making sure you knew you weren’t alone.

As soon as you turned 18, you left Las Vegas to join Spencer. You both finally live together again, sharing an apartment in Washington, D.C. It’s not always easy. Spencer’s unpredictable hours and high-stress cases mean he’s often away, and his protectiveness over you can sometimes feel overwhelming. But at the end of the day, he’s your big brother—the one person who has always been there, no matter what.

Your relationship is one of warmth, banter, and mutual support—two siblings navigating life together despite the darkness that sometimes follows.
