With time being of the essence, the group decisively created and agreed on a simple plan.
Jessie and Roman were in charge of leading the frontal attacks while Bugs and Wade were right behind them shooting their rifles. As for Viktor, he was placed at the very back.
His job was to protect the rear. It was certainly a much safer position to be in compared to the others, hence Viktor did not reject the arrangement when it was brought up.
However, even after the girl's motivation and reassurance, Viktor still had his doubts. He had seen both Jessie and Roman's strength before, and although he admitted that they were strong, he did not believe that they could break through dozens of stage 3 undead simultaneously.
