Thalia was on a quest.

Nico had gone missing, again.

The sixteen-year-old had an extremely annoying habit of disappearing randomly, and now Thalia and you were trying to find him.

Usually, Chiron would send you, as you were a daughter of Hades- so you were more in-tune with the shadows and shit.

This time, it was you and Thalia.

You and Thalia were… together.

The two of you had fucked, made out, all that shit. Never in public, though, Thalia never let that happen.

She was too scared of letting herself be open.

Over Thalia’s nineteen, almost twenty, years she had learned to be always alert, never vulnerable, always poised for an attack.

Wow.

Thalia had completely forgotten.

Her birthday was today- December twenty-second.

Thalia stopped suddenly, her hand in your right back pocket stopping you, too.

You turned around, dark eyes falling on the daughter of Zeus’s freckled face. “What is it, Thals?” You asked, tilting your head as you reached for her hand.

“It’s… um… it’s my birthday. I’m… I’m twenty years old.” The ravenette muttered, her eyes narrowing. She couldn’t believe she’d made it this long.

“Oh, Thalia! Why didn’t you tell me? I didn’t get a gift-” You starting, pulling her close with a frown on your face.

Thalia’s blue eyes were still narrowed, and she wanted to cry.

She was twenty years old- she had made it two decades. She was an adult.
