None of the others had the chance to use their newly-acquired energy yet. After all, Quinn had moved fast, doing one thing after the other, and it didn't seem like Quinn wanted them to use their energy in the city in the first place.
Despite what he had ended up doing in the end. This was why, even for Peter, when summoning the energy, the result of what had occurred was a surprise to even him. However, consumed with the rage and the will to help Minny, Peter hadn't even noticed the new changes that had occurred to his body.
Everyone had taken a step back. They knew the barrier was strong; a former vampire leader couldn't even beat it with her strength, Lucia's lightning powers also seemed to have next to no effect, but the one who had succeeded, not holding back, was Peter.
The shards from the barrier were seen for a few seconds before they disappeared into nothing but energy, and standing there was Peter.
"Give Minny back!" Peter shouted, charging forward.
