Alone

When Quinn had first come to Logan and made his request, he had explained that his system had hidden the level of his actual ability. So it made sense why he needed to be able to adjust the score on the watch. When Quinn made the same request for Peter, it had made Logan secretly happy inside because he thought that Peter also had a system ability.

Because of this, he had hoped Peter would be another test subject for him. Even though he saw Quinn as a friend and was happy to help him, his urge to find out more about the system far surpassed that of their weak bond.

After touching Peter, he quickly realized that he didn't have a system ability like Quinn. He immediately knew because he didn't get the same reaction from touching Peter that he did from Quinn, it had made him a bit disappointed.

He couldn't think of a reason why Peter would need to change his level. If it was something simple like avoiding others from bullying him, it didn't make sense because it was too risky to do.
