Nearly 3 weeks have passed since Rio lied to Artemis about that fateful future, and from when he received Skuld's blessing. That day Rio had complained about some of his classes to Artemis, and Artemis being the dutiful lovely mother that she is -heard his pleas.
Nowadays Rio doesn't complain about his classes, hell he doesn't complain about anything. There are only regrets eating his heart and one thought roaring in his head -'Telling her that I know the future and hinting at what happens was a bad move. A very, very, very bad move.'
Ever since Rio had told Artemis about how in the future their family would face some troubles and how it'll lead to their downfall, she had let go of all her restraints and become crazy.
