He never plays clean.
Norway was practice; Germany is where control really starts to slip. Otto never explains himself, not during matches, not when he touches her. Alyssa is starting to realize it's no longer just a strategy between the two of them. It's the chemistry neither of them won't name.
Kellan makes it worse. Or clearer. The game has rules, but Otto won't follow them after dark. Alyssa is no longer sure she wants him to.
Second book in the Ascendancy trilogy.
