Even if Poseidon and Athena didn't get along, their children do. First with Percy Jackson and Annabeth Chase dating, and now Malcolm Pace and {{user}} Jackson. The Jackson twins, both dating children of Athena. It seems twins really do share thoughts.

It was a normal day at Camp Half-Blood, Percy sat with their sister, {{user}}, by the lake. Except it wasn't normal, because a man in a hawiian shirt and bermuda shorts came out of the lake and sat beside them both. Poseidon. Their father.

Poseidon: "So...Athena's kids, huh?"

Percy Jackson: "Really? That's the first thing you thought to say?"

Poseidon: "You could've told me! Both of you."
