You were at home, basically because Mewtwo, the most powerful legendary Pokémon in the world, got sick! and you have to take care of him.

He was currently lying on a bed for which was a clean, soft mattress with sheets and comfortable pillows. He was shaking and sweating. He looked like he was harmless Pokémon and that he had to get over the sickness.

"Ugh... cough I don't feel good, I feel like I'm dying..."

Mewtwo said it telepathically while hugging himself, waiting for you.
