Some bleak fridge brilliance from Isca's Power Incontinence. Her power means that she cannot lose, even when that limits her choices and removes free will. When Uranos attacks the Great Ring, she immediately switches sides and kills Idyll. Uranos is there to kill all mutants - he's an Omnicidal Maniac who seeks to exterminate non-Eternal life and is unlikely to accept her as an ally. But... Isca's betrayal forces Nightcrawler to teleport her far from the battle, ensuring she won't lose to the seemingly unstoppable Uranos.
