So, I said ‘Okay, I’m going to Orlando. Let’s go.’ She went up with me, she jumped in the ring, and she loved it, man. She was hitting the ropes, rolling. I know you said the tumble. She was doing all that. Like the generic stuff, basic stuff, beginner stuff. But, yeah, the ring brings it on another level, man. It’s crazy, especially the ropes. When you hit those ropes, she was all bruised from her back," he said.It will be interesting to see if the Triple H-led creative team has planned anything for Aalyah Mysterio's potential future on WWE TV.
