Alone

Stanley saw Gray's dying body fall to the ground, with black mist dissipating around him at the same time.

"Gray!" he shouted in disbelief. He couldn't understand how Gray had been attacked. Good thing he had marked him earlier.

He quickly turned back time, now a hundred-fold faster due to his ability to slow down time coming back. Both his Time Reverse and Time Speed-Up powers were tied to the rate of how much he could slow down time.

While his power was gone, the rate was normal. But now that it had come back, it improved every other power at the same time.

Gray's dying body healed in an instant, going back to how it was before. For some reason, however, the reversed time did not affect Gray's mind or memory, so when he was healed, he only looked all over himself, confused and surprised.
