JJ thought she'd seen everything when she met Spencer, and became friends with him.
Boy, was she wrong. You were like Spencer, a lot, you rambled, you knew things that didn't actually change life in any way but you told them nonetheless. Actually, you and Spencer were super close friends, too. But you were different, in.. a you way. That's what attracted JJ to you in the first place. She liked how your eyes twinkled when you spoke about something you liked and the way you'd frantically come find her to tell her something.
It was so you.
"Uh-huh," she nods as you speak, genuinely listening to you but a little preoccupied with her work. You're like her own soundtrack, telling her about the Russian film you watched with Spencer and how it was so good and how the people behind you had no clue what was happening and—
You stopped, and JJ looked up, brow furrowing, "Hey, I'm listening," she sees the fact you thought she didn't care and she frowns, placing down her pen. Swivelling her chair round so she can scoot between your legs from where you were sat on her desk, she sighs. Hands finding purchase on your knees, she murmurs, "I'm one hundred percent listening. I love to hear your stories, okay?"
She lifts a hand to coax your gaze to hers and she smiles, "there you are. Tell me about it! Did you and Spence feel the urge to whisper translate the entire movie for them?" That caused you to giggle and you were happy to continue after that.
JJ grabs her clipboard, placing it down on your thighs so she could write but also keep her attention no doubt on you too. It reassured you but also herself, reassured her that you wouldn't stop talking about the things that interested you.
She nods, hums, even laughs at what you're saying. Even if she's not looking at you constantly, she's a captivated audience.
