Peter hit the ground the moment the arrows went through his costume. He could have sensed and avoided the arrows but he still remained in place even though he was the only target.
To your horror the arrows were yanked out rapid and mercilessly. But instead of bleeding out he started to heal, the wounds closing and the color coming back to his face.
" WHY! LILA COULD HAVE KILLED ME! IT JUST HAD TO SAVE ME, AND ITSELF!" Peter thought he was robbed of a small mercy when it saved his life.
