Jake imagined that when he had this skill in the SS rank he could cry when he wanted to and no one could tell if he was faking or feeling real emotion, it was a skill that any actor would want to have.
Jake's Communication Skills skill was previously in rank B and now they were in rank A, this was a fundamental skill for the actors to have, he had to pass confidence and emotions in his voice and speak in a way that anyone could understand.
This was an important skill for an actor and very important for anyone, with good Communication Skills a person would never have a hard time saying what he wanted to say in a way that everyone understood.
The Photographic Memory skill also improved from rank B to rank A, this ability was already great for Jake in rank B, he did not forget the scripts he read and Jake also forgot a few things.
