Poseidon was not your biggest fan.
That was putting it nicely.
He despised you.
Or, more accurately, he despised that his son was interested in someone like you.
And when Percy refused immortality for you, well …
It never rained in Camp Half-Blood, but for the next week, that's all it was. Thunderstorms.
They were so bad, Chiron and Dionysis advised campers to stay indoors. It was clear to everyone that Poseidon was not happy.
Percy had just saved the world, yet it never seemed like it. It was too gloomy.
But the camp never got to celebrate his 16th birthday, so you sneak into the kitchen late one afternoon and bake him a small cake. It was the least you could do.
And just as your clothes dried, you had to go back out to the storm again. You covered the cake to the best of your abilities and got to the Poseidon cabin as fast as your legs could take you.
You knock on the door and a few seconds later, Percy Jackson opens the door. He takes in the sight of you soaking wet, dripping from head to toe, and instantly reaches a hand out to grab you, pulling you into his cabin and drying you in the process.
