Through the Door of Space-Time, Setsuna, a.k.a Sailor Pluto, ran with a toddler in her arms, weeping. She knew she should not have done what she did, but she hoped her actions to correct her mistake were enough to make up for it. Sailor Pluto had used her Garnet Rod/Garnet Orb to open an alternate dimension, where instead of Prince Endymion marrying Princess Serenity, he married Sailor Pluto, now Princess Pluto! In reality, Sailor Pluto knew Prince Endymion loved Princess Serenity, but this made Princess Pluto less lonely and very happy. To add to this, Sailor Pluto found out her alternate reality had a daughter too!

A now 4-year-old mirror image of Sailor Pluto, except with wavy, brown hair, green eyes, and for some reason has a scar over her right eye. Sailor Pluto wished she could stay and observe her, but she did not know how long she had. Thankfully, she saw enough to know she was in Charon Castle, her palace, which looked like a ruby-colored dark crystal with red energy swirling around it and bumped into her doppelganger early on. Normally, this would be one of those time paradox situations, but it seemed that theory was not true (Ex. Identical twins are a thing, and if that's acceptable, why not a similar thing here?) Princess Pluto pointed her Garnet Rod/Garnet Orb at Sailor Pluto!

"Who are you, impostor?!" Princess Pluto demanded.

"Please, allow me to explain: I am the keeper of the Door of Space and Time. I am Sailor Pluto, Guardian of Revolution and the Underworld. More directly, I am you...from an alternate dimension." Sailor Pluto believed telling the truth might actually get her by.

"You've done your research but cooked up a lousy story. I have never experienced my powers opening an alternate dimension, and anybody could know of my connection to Revolution and the Underworld." Princess Pluto snapped.

"This...is the result of me testing my powers. I did not mean to willingly trespass, Princess. How may I prove I am who I claim?" Sailor Pluto asked.

"Hand me your Garnet Rod. If you are who you say, they will resonate." Princess Pluto held out her hand.

Without hesitation, Sailor Pluto handed her Princess self the rod. When Princess Pluto touched it, the Garnet Orb began to glow! Princess Pluto was dumbfounded, but all Sailor Pluto felt was a relief.

"Do you believe me now?" Sailor Pluto questioned.

"There could find no truer evidence but, if you are me, why are you not a full-fledged Princess?" Princess Pluto asked, confused.

"In my dimension, I am not married to Prince Endymion, so I can only assume my Princess form on my home planet. Who is guarding The Space-Time Door?" Sailor Pluto looked alarmed.

"Don't you worry, Diana is guarding it?" Princess Pluto smiled.

Though Diana did not exist in Sailor Pluto's timeline yet, the guardian knew Luna and Artemis's future daughter.

"Oh. Where is Princess Serenity?" Sailor Pluto looked around.

"As different as things are in your dimension, so are they here. Princess Serenity has been long gone." Princess Pluto explained solemnly.

"What? That's impossible! How?!" Sailor Pluto screamed.

"While myself and the other Sailor Senshi were revived, thanks to our Star Seeds, Sailor Moon's battle with Galaxia was too much on her. Even with Galaxia turned good again, Sailor Moon gave into all her fear too quickly, and there had been so much building, it destroyed her Star Seed." Princess Pluto's eyes, shining with love only a moment ago, remember the sweet, small, gray kitten now shimmered with agonized tears.

"That almost happened to her in my dimension too...W-Who has taken over the hierarchy?" Sailor Pluto could not help crying a little too.

"Galaxia, the good her. We feel it only right as it was her body, which was used to kill Princess Serenity." Princess Pluto replied.

"I see." Sailor Pluto conceded.

"Mommy?" Trisha's voice, soft but clear, sounded as she peeked into the room. When she saw Sailor Pluto, she exclaimed in happiness, "Two mommies!" And she hugged Sailor Pluto's legs.

"No, Trisha, I'm n-" her royal self cut off sailor Pluto.

"Actually, your dimension must be so much more wonderful than my broken one. Trisha has been through so much in her short 3 years of life. You see that scar over her eye? Last month, we were attacked, and Trisha had swiped my Garnet Rod; she had seen me use it many times and thought she knew what she was doing. She used Dead Scream, and though it repelled the evil, it had struck her too. Luckily, the wound is not severe. Still, she deserves a better life than the one I am giving her. Would you mind adopting her?" Princess Pluto picked up her daughter and looked Sailor Pluto dead in the eyes.

"You want me to adopt her?! While my dimension is wonderful, I can't take a child from its mother. Even if I do, the door to this dimension will close in time, and I'm not sure if I can ever re-open it. You'll never see your daughter again! As broken as this dimension is, Trisha sounds like she isn't suffering. I don't even know anything about her! What about Prince Endymion?!" Sailor Pluto exclaimed.

"My husband won't mind as he knows I will always do what is best for our daughter. Trisha likes friends, physics, green tea, shopping, sewing, and fashionable hairstyles but dislikes bugs, eggplant, music, and intruders. Her birthday is Dec. 29th, and if you need more information, her blood is type is A." Princess Pluto laughed.

"That's all well and good, but still-" Sailor Pluto was about to refuse but noticed her time here is almost up.

"Please, take her! Give her a better life!" Princess Pluto pleaded, holding her daughter out to Sailor Pluto.

Unable to have any more time to think, Sailor Pluto grabbed Trisha just as the Door to Space-Time closed! Now, on the other side, Trisha knew something BIG had happened.

"Mommy 2? Where mommy 1?" Trisha asked as her scar started to disappear, replaced by the symbol for Pluto glowing pale lilac on her forehead as the time paradox changes started affecting the little girl.

"Trisha...I'm so sorry!" Sailor Pluto hugged Trisha, sobbing louder and harder.

Trisha began to cry now, too, knowing that she would never see the mother she recognized ever again. Much to Setsuna's dismay, Trisha grew up a lonely child. Trisha did get to see Neo-Queen Serenity, King Endymion, Sailor Senshi, Luna, and Artemis. Luna and Artemis informed Setsuna that Trisha is the new Sailor Pluto, seeing as she literally traveled through space and time without showing any weakness. Her duty to the Door of Space-Time began as soon as her fifth birthday starts. The Door of Space-Time...Setsuna almost forgot.

Explaining what happened to Neo-Queen Serenity, Setsuna promised she would quit being a Sailor Senshi. She felt her unrequited love for Endymion being fulfilled in that other reality is a dishonor. She will seal the Door of Space-Time, seal off the alternate reality with Dark Dome Close. The Moon Kingdom will never have to be troubled by them again.

"Setsuna, stop that! Though this is all shocking, I don't blame you. You made the right choice to take Trisha, and I don't want you to punish yourself or her. Endymion doesn't mind Trisha being here. You have never dishonored me in any way either." Neo-Queen Serenity made it quite clear she wanted Setsuna to remain a Sailor Senshi as well as her daughter. Still, she did not want Trisha growing up as lonely and sad as Sailor Pluto did, so she allowed the young girl to attend all Sailor Senshi-related events.

Sailor Pluto did close an alternate reality as she had promised. By this point, Trisha did not care and had accepted Setsuna as her mother. Setsuna spent as much time as she could with Trisha in Time-Space. Trisha proved a quick study of her powers with her own Garnet Rod/Garnet Orb and became a serious, silent, watchful, protective, swift, and fierce, yet a bit shy. Setsuna could not contain her joy: Trisha was not going to be as lonely and sad as she had been, AND she was every bit as much Sailor Pluto as Setsuna herself!
