The monster's mass far outclassed Mark's own and that meant that he could not stop the incoming charging person without any support of his own. He dodged the mass by an inch which caused the mutated person to crash into the tree behind him.
He already knew what the beep in his system was about so he did not bother to check it. his first priority was his own life and then anything else.
The other shook off his shock far too easily for Mark's comfort and he was charging once again. Mark tried to lead him off toward the side area, all the while keeping the vial in his sight.
Since it was such a small thing, there was no guarantee that he would be able to find that again even if he marked that area. The small monsters that roamed this area could pick that thing up by mistake and then it would be lost forever.
However, that was a pain too since it meant the monster had much less region to cover than before and it stopped Mark from making too wide moments.
