The scene where Layla is attempting to murder Jade is given its own animation. Scarlet is in tears, disgusted by how vicious the fight has become and demanding an end to it. She even offers herself as a prisoner to get Layla to spare Jade. ...And then Layla kills Jade anyway.
Scarlet then has to endure being lied to a second time when, after bonding with Cosmog and evolving them into Solgaleo, Layla and Mumkey absorb them into Necrozma. No wonder she's suicidal in the next episode.
