Originally, Chris was slightly concerned for Peter, even if he didn't openly show it. This was because Peter was going against not just one opponent, but essentially three.
There was the demon tier shadow beast that was controlling the vines, Geo, and Nock. He had no clue where the demon tier Owl went. It seemed to have disappeared after getting hit a few times.
However, Geo was fine with this, because he was sure that it was being used to support other areas. After all, while they were fighting against these two, there was Jim himself, as well as the original vampires all still fighting.
The truth was, they were annoyed that this had taken a lot longer than they initially thought. As time went on, there was a large amount of pressure going on in Geo's mind about the fight, which was perhaps why he was pushing himself.
