Re: Rey Mysterio heel turn a possibility against Sin Cara at WM29!
Some things just won't work: Mysterio turning heel is 1 of them. Sin Cara I could see as a heel though.
The Ultimate Warrior's RAW speech:
Every man's heart one day beats its final beat, his lungs breathe their final breath and if what that man did in his life makes the blood pulse through the body of others and makes them believe deeper in something larger than life, then his essence, his spirit will be immortalised.
