If you're referring to the events of Recollective Musicbox and Survival Ma, you can read the events in our articles for Irina Clockworker and Elluka Chirclatia. Irina stabbed Elluka in the back, leaving her the last candidate to be selected as a test subject.

As for the Duel of Merrigod Plateau, we're still updating articles from the Pierrot novel, but you can read what occurred in the previously linked article and Ma.
