The HEARTBREAKING reason WHY DARTH SIDIOUS personally called each of these Clone Commanders to execute their Jedi during Order 66, after killing Depa Bilaba. Captain Rex, Commander Cody and Commander Grey were all personally called by Darth Sidious / Chancellor Palpatine to execute Order 66 on their Jedi: Ahsoka Tano, Obi-Wan Kenobi and Depa Bilaba & Caleb Dume/Kanan Jarrus.
