JD went by outside of the Tsukino residence. He is loitering by his motorcycle, waiting for Serena to come out of her house.
"I get the feeling her mother didn't took well of her getting bad grades," he muttered.
Of course, he's right when he witnessed Serena getting kicked out of the house by her mother.
"Go to the library and study for your exams!" the latter exclaimed.
As JD witnessed this at first sight...
"I hate her for how she treats her daughter whenever she gets bad grades," he commented on Mrs. Tsukino before approaching Serena and putting a hand on her shoulder to give her comfort. "Hey, are you okay?"
"Yes, I'm okay," Serena tried to smile.
"You don't look okay."
"Hey, aren't you that new student who is a rebel?"
"Why, yes I am. It looks like you need help in your studies, so I come here to pick you up and study together at my place," JD suggested with a hand. "What do you say?"
"Okay, I accept."
JD takes Serena on his motorcycle. Before they go...
"Hold it right there, Serena!" her mother exclaimed as she interrupts their ride. "You're not studying with this guy! He's a bad boy!"
"You're just jealous because you're acting like a bad parent to her," JD said with a smug smile.
"Bad parent?" Ikuko looks offended upon hearing this from him.
"You heard me. I suggest a bitch like you do what's best for your daughter by letting her study with me because I'm smart."
With this, JD drives off with Serena, leaving a pile of smoke to her mother which she started coughing. While on the road...
"JD..." the girl said.
"Hmm?" the boy got her attention.
"What you did to my mother back there is not nice!" Serena called out.
"Well, for my opinion, she deserved it. In fact, it's about time for you to stand up to her whenever you get bad grades," JD explained. "To tell you the truth, what she does to you reminds me of my father whenever I get bad grades."
As soon as the two are in his home, they're in his bedroom, ready to study together.
"Now, Serena, can I see your test paper?" he demanded her to hand over her paper, and she does it. Upon looking at it, she has a low score of 30 over 100. "Are you going to take a re-test?"
"At Monday," she replied.
"Well, let's get started. I'll teach you how to make the right equations in your subject, but before that, I want you to tell me something."
"What is it?"
"You're hiding something from me, aren't you?" JD knows of the girl's secret.
"Me? I-I-I don't know what you're talking," Serena tried to keep her secret hidden from him.
"Don't play dumb with me. I know there's a reason for you to keep your distant from your best friend," he explained before putting a hand to her. "Come on. You can trust me."
At the moment of truth, Serena grabs a brooch, and exclaimed.
"Moon Prism Power, Make Up!" she exclaimed as she is covered and JD shields his eyes. After being covered with light, she wears a costume that is so familiar to JD. "Here is my secret, JD. I'm Sailor Moon, the Sailor Scout who fights for love and justice!"
"I knew it," JD said calmly.
"Huh? You do?" Sailor Moon asked.
"The first time I at school, I already knew, and so are you friends. I can't believe why Molly can't see through that."
"I'm lucky she didn't, so please, JD, don't tell her about this."
"If you insist, I won't, but you will have to show this to her someday."
"I will."
"Well, now that you've shown me your secret, I'll help you study for the make-up."
JD proceeds to help the Sailor Scout study for her test on Monday.
