Afraid
Laxmus had yet to use his power in battle, and Peter knew this. Nevertheless, he hadn't moved from his position, and there was a confident smug look on his face even after Peter had defeated one of the guardians and the shadow beast.
In all honesty, Laxmus had only shown the power of his shadow, and it was enough to make them struggle, which was why Peter couldn't imagine the strength in his transformed arm if he was to be hit by it. Thankfully though, Vincent was there, and Peter noticed the special sword in his hand.
Watching the fight go on, Logan was tense up till this moment, almost biting off his fingernails.
"Arthur's sword... It was with Vincent? I always assumed it could have disintegrated into the red heart, but if Vincent has it, it's getting more and more that he has the red heart."
It was then that a thought had clicked in his head.
