No he is getting X Pac aka Go away heat, not heel heat, there is a difference.
No its not go away heat, its heat for taking Bryan's spot it is as simple as that, why do you think Mysterio got booed when he came out at #30? The crowd saw Mysterio take a spot that should have been Bryan's just like how they feel Bryan should be the rumble winner, that is the catalyst to Batista's heat.
If it truly was go away heat, he would have gotten just that his first night back on Raw. Let me ask you this if Batista didn't win the rumble and engaged a program to settle with Alberto Del Rio would he have gotten this "X-Pac heat" you speak of? I can answer that. No. Why? Because of Bryan's spot being secured.
