Tyrone was frozen, unsure of what to do. Ren wasn't an enemy, at least not in his eyes. He didn't want to make an enemy of Ren either. He knew just how much stronger Ren was than him, and the fact that even Sia was frightened showed it, considering the woman never seemed terrified of anyone.
Sia was, in fact, frightened. The energy that came off Ren wasn't something she was used it. The winds, in particular, felt cold and deadly. A familiar feeling, one that she did not enjoy and hoped to ever bear witness to again. She had felt it momentarily when he first unleashed his power, but now that got more of a feel, she could never mistake it.
