Both arms slipped in a downward direction and so did the head fall
But to the surprise of the perpetrator of the act, before the body parts could fully drop to the ground, they reattached themselves to where they had come from.
This time Max's regeneration had processed a lot faster than it had ever done. And instead of growing new arms, and perhaps a new head? his cut off parts coupled themselves back into the position they were supposed to be.
Was it because the impact wasn't as effective as the cuts he had ever received? so his arms and head didn't just fall to the ground immediately as a result of that and was able to reconnect themselves back due to the short distance between the parts and the rest of his body.
