Monster, Giant Flea What's the diff?

The Professor's Task

6 days later I returned and Charles greeted me and let me in. First impressions mean a lot to me and my first impressions of the Gardens was amazing. He had so many different plants all living under the same roof including a large Sequoia tree. Passing the jungle like nature of the Gardens, in the back was the Professor. He had a white beard, wore a yellow trench coat and had a round pair of glasses intensely staring at an eye dropper he was holding. Charles told me to stay a bit a ways from the Professor's space as he slowly approached him and slipped the Professor a card. He let a drop fall from the eye dropper and looked up to me just as the drop exploded in to a cloud a purple. He started coughing but continued to say "Hello, hello! I haven't had a visitor in a while  besides Raoul. Come, come! And introduce yourself will you?" He had such a cheery tune even though he seemed old and I noticed some what worn as I got closer to him.
"Hello, Mr...?"
"Everyone calls me Professor dear, it's all right."
"Well hello Professor. My name is Vianna Kelentza."
"And to what do I owe the pleasure of having you visit me today?"
"I heard you are a great chemist so I moved here to see if I could become a student of yours."
"Hohoho! Well my dear, I am afraid I am not particularly looking to teach any one my skills and I already have an assistant." At the mention Charles moves to the Professor's shoulder.
"Are you sure you don't need any help on the research of the giant flea in Paris?" From the moment I said giant flea Charles had a finger to his mouth and when the Professor noticed he suddenly stopped.
"What giant flea?" The Professor's tone grew more serious then cheerful and it made me hesistant to continue. Maybe it was a touchy subject but nonetheless this was my chance!
"The giant flea I assume was created in your lab and escaped that then proceeded to "terrorise" the town and became a famous singer in the Rare Bird."
"Wait you mean that new talent monsieur Francoeur?"
"Yes, his existence troubles me and I thought it would trouble you sir."
"Please tell me what you know Ms. Kelentza. I just arrived yesterday so it seems impossible to me that I created it and news of these things I never catch until much later."
"Well when I came to ask to be your apprentice is was about 6 days ago. Charles can confirm. The next day talk of a "Monster in Paris" was all over the newspapers and streets. People were afraid to go out. Then a new talent appeared at the Rare Bird just 2 days later. I went to one of the latest shows and I wanted to meet Mr. Francoeur since he had such a lovely voice but Lucille stopped me. She didn't have a very convincing excuse and half way through it Francoeur came out with out and even with his mask I could tell he wasn't human. Lucille pushed him back in closed the door and basically kicked me out. Paris believes the monster is gone but he is still here in Paris. I got more information about the situation from the new Commissioner. He told me Francoeur was a flea but he had never hurt a single person since his appearance. Which it really great but he is a flea, how can he not hurt someone?"
"Yes I am starting to see the predicament here. Hmmm." I let the Professor think it over for a few minutes until he finally said "I will allow to become my student."
"Really?!" I was so happy but he stopped my celebration.
"If you can give me a good report on monsieur Francoeur's status."
"Of course!"
"And you will not harm him too observe him?"
"Yes, I won't harm him for more data."
"Good girl. Now off with you, you have some data to research and I need to have a chat with Charles and some others I know are a part of this."
"Of course sir! Thank you sir!" I bow my head and turn to leave.
"Thank you for this info Ms. Kelentza and should you discover he is a danger to society please notify me and the police immediatly."
"Yes sir." And with that my task was clear.
