- "Don't call me an idiot! I'd kill you if you weren't my brother!"
- ― Scream to Rage
On September 4, 2019, Elke and her brother flew over to Artiglio Port in order to engage the Long Range Strategic Strike Group, who were escorting an Osean Navy fleet attempting to capture the Alicorn. Despite Rage instructing her not to, Scream shot down an Erusean aircraft prior to engaging Trigger. She retreated alongside her brother after the dogfight.
During Operation Domino on September 10, 2019, Mimic Squadron once again attacked Strider Squadron, this time as they prepared to withdraw. Striking Lanza's aircraft with stealth missiles, the siblings engaged the 2 remaining Strider aircraft - Trigger and Count. As the dogfight raged, Clemens contacted the Mimic team on an open channel and ordered them to withdraw. Rage refused, telling Clemens it would be a blow to their reputation. Clemens responded by calling the two "goddamned idiots", prompting a verbal threat from Scream. Despite them using stealth missiles and ECM, the siblings were both shot down. In her final moments before her plane exploded, AWACS Long Caster ordered Scream to eject. Scream refused, telling them that while Rage would go to heaven, she would wait for Trigger in hell. Scream's plane then exploded, killing her.
