What was Ernst's personal or political relationship with Hitler?

Toward the end of the war, Kaltenbrunner's power increased greatly, especially after the attack on Hitler of 20 July 1944. He gained direct access to Hitler. He was very friendly with Fegelein and his wife, who was the sister of Eva Braun. So powerful had Kaltenbrunner become toward the end that even Heinrich Himmler feared him.
