Well that fight with Iggy was absolutely embarrassing for Pet Shop. Pet Shop isn't even going to question how the absolutely hell he was alive after that, divine intervention maybe? Who cares. All Pet Shop cares about was his bruised ego and where the heck was he going to go now. He can't go back to Dio! Not after that mess! Too embarrassing ... Pet Shop decided it was better to simply fly off and try to live a normal life. ..Try.
