3x21-I assume Savitar's speed armour protects him from ARGUS nullification fields but there are surely better places to hide Iris than just standing around in STAR labs.
-DEO in Kara's Earth where she'd be protected by Martian Manhunter and Supergirl? -The Fortress of Solitude in Kara's Earth? -Batman's moon base in Kara's Earth? I assuming he has a Moon base, he normally does. - Somewhere in time with the Legends on the Waverider? - Or Barry could just kill himself already. Savitar's excuse for why that wouldn't work in a previous ep was laughable.
