At Casper High, Dawn and Toy are talking about Dawn's knowledge of Mari Fenton being Mari Midnight.

"Dawn, are you still sure you're doing the right thing by not telling your family you already know your sister's secret?" Toy asks.

"Yes." Dawn calmly replies. "They should understand it'd be easier to tell me. Why, Dad once feared his own parents would reject him. He should have told me. Or at least told Mari to open herself rather than encouraging me to keep the secret."

"If you really believe it'd better have it all open you should tell them you know." Toy says in return.

"Fine, I'll think about that." Dawn replies upset.

Meanwhile, Danny and Sam are talking about Dawn's sudden change of behavior.

"Sam, I can't understand what's wrong with Dawn." Danny comments. "She's been acting so weird since that body-swapping incident."

"Well, you know about this better than any of us." Sam replies. "Don't you remember Poindexter?"

"Yes, but nothing of this makes me understand Dawn." Danny answers.

"Well, maybe she had found out about Mari and upset that we didn't tell her." Sam theorizes.

"Sam, if Dawn knew about Mari she would have talked about that." Danny replies.

"Don't you remember Jazz?" Sam asks in reply. "Once she discovered you're Danny Phantom she decided to keep it to herself. Maybe Dawn decided to do the same."

"Point taken." Danny replies. "But I'll talk to Mari before checking this theory with Dawn. It's not our secret to tell after all."

Sam nods.

Later on, Dawn arrives at home.

"Mom, Dad, there's something I have to tell you." Dawn says.

Time skips to when Mari arrives.

"Hi, sister." Dawn says with a malicious tone. "Did you fight any ghosts today?"

"Well, there was Skulker and then..." Mari stops answering as realization clicks in. "I mean, no. I don't have ghost powers."

"Come on, Mari Midnight, did you really think I wouldn't find out anything during our body-swapping experience?" Dawn asks in reply.

"Busted." Mari says, realizing there's no more point at denying. "But why did you wait until now to tell me?"

"When I learned Mom and Dad knew and neither told me nor made you tell me I became upset." Dawn explains. "They should know it would be better not keeping the secret from me and that I would accept just like our grandparents accept Dad."

"Sorry, Dawn." Mari says.

"Apology accepted." Dawn replies. "Hey, now that all of us know the truth, will you go public or keep it a family secret?"

"I admit I never thought about that." Mari sheepishly answers.

THE END

Did you like it? One of the reasons I stopped this fic is the fact I hate the fact TPcrazy removed her sequel to Mari Midnight because of that. I wanted to see Dawn learning Mari Midnight's secret for good in their creator's writing. Please review.
