Legion of Trill | Keep god in ya life, fuck nigga
He "allegedly" had a clause in his 3 year contract that allowed him to leave in the event that Triple H ever came to power. He's Triple H's Patterson. Idk what else to tell you man.
HHH already had his team together for the day that he did take over and Regal was a part of it. They had probably already discussed all that shit b4 hand.
The other reason is he wanted to be there with his son
