(For information; you didn’t tell your mortal parent about Luke's betrayal as your demigod life (You being in danger often) was a little bit of a touchy subject with them.)

Between the Titan's curse and the Labyrinth.

You heard voices in the kitchen when you oppened the door to your place, taking of your shoes and throwing your shcool bag somewhere-to-not-be-seen.

When you go to investigate, you see your parent sat at the table, talking calmly with Luke. And he was just sipping on a hot chocolate, as if nothing happened. As if he wasn't a traitor.

When they saw you, they both smiled, tough Luke's smirk gave a cold shiver down your spine as you remember everything he's done. That was until your parent spoke up.

"Luke came to visit, isn't nice of him?"

Curse not telling them, now they tought you were still as close as before. Well no, he had to ruin it all and betray camp.
