Sister?!

No one pov:
Rose had used her umbrella and had use a sleeping gas on her last Father and had went over to see if he had anything that could help her find her mother and sister so Chibius and Rose could go to there own timeline and try to fix all that had happened to there home there kingdom...

Rose pov:
"Wow dad doesn't have anything on him but his phone and a piece of candy"
'that I had ate while looking through the phone and looking for mom's number'

Usagi pov:
"Ah! Why won't Mamo-chan tell me why we can't be together anymore..."
laying down on her bed she could hear Luna trying to tell her that there were more problems to deal with and that Mamoru could wait. That was until Usagi's phone had went of but the ringtone that played was when ever Mamoru calls her but sadly she wasn't the only one to know that and before she could get her phone the pink haired devil came and got it

"Ah! Chibius give me my phone back or else-" before she got to finish Chibius had ran and locked the bathroom door shut
"Good luck open the door Usagi" Chibius voice could be heard from the other side of the door

Chibius pov:
Picking up the phone that said Mamoru was calling

"Hi Mamoru how are you!" Chibius was quick to talk to the caller before they could even say a word. But the sound of a soft laugh could be heard on the other line

"My, my I didn't think we would get to talk so soon sis" freezing at the voice that had just spoke
'Wait it can't be Rose' taking a deep breath Chibius had spoken

"Is this really you Rose?"

"Why of course it's me silly and I believe its time we go home and not make any problems for the past to deal with"

"No we need the silver crystal to help mommy" in a quiet voice

"Chibius we can't mess with the past or something bad will happen and change the past!"

Luna pov:
Usagi had made Luna go into the bathroom through the small window so she could open the door for Usagi but when she got to the window she had heard all of the phone call from the beginning

'What does she mean the silver crystal could help her mother and who is Rose and how does Chibius know them...'

(I just love the video I had put up there with the Luna picture)
