I had this idea and wanted to wait to see if anyone uses it first. The closest I found was Did our Kid just Time-Travel into a Warzone? by naiadNyx.

"Don't you get it? I love you! I always have!"

That was from the holographic memory recordings from the First Ones technology, Adora had Entrapta take the technology and build it into the previous She-Ra Darla's old ship. Adora and Catra would come to the ship to relive some of their memories together, not like when Light Hope shown them certain specific memories in order to drive them further apart and destroy chances of reconciliation at that moment (which Adora guessed in retrospect was intentional due to Light Hope trying to mould her into completing the First One's Heart of Etheria Project). No they would view the memories of the good times together that solidified not only their friendship but their love as well.

The Horde and Horde Prime was gone and so Adora along with the Princesses and former members of the Rebellion helped to rebuild Etheria, along with the repentant former members of the Horde including Catra. After they had destroyed Horde Prime and realised their love for eachother, they worked on working through their issues and starting anew with their relationship.

Adora and Catra had gotten married in a ceremony attended by the Princesses, Rebellion and their former fellow Horde cadets with Catra managing to patch things up with them. She was forgiven by them in time after she apologised, admitting that she won't blame them at all if they never wanted to see her again. Bow was the Best Man and Glimmer shared the Maid of Honour position with Scorpia.

They their own non binary Magicat child that they named Finn; when they decided after some time figuring it out while discussing it with eachother, that they wanted to be parents then they will make sure that their child would have the happy healthy childhood that they were denied growing up in the Fright Zone. They both taken parenting classes and Catra especially was dead set on making sure that their child always knew that they were loved and mattered.

They pretty much spoiled Finn with not only toys but love and attention, but would tend to overreact whenever they got sick or a bruise. Finn found it overwhelming and at times wished that they were staying at Aunt Perfuma's.

Right now Adora and Catra were out on a retreat with the other Princesses with only Entrapta not attending because she was desperate to work on some First Ones tech that she had found. She along with her husband Hordak (having served his time helping restore Beast Island) and Wrong Hordak who now worked at her castle. Finn's favourite babysitter was Double Trouble who inspired them to want to become an actor but they were in the middle of something on the other side of Etheria with a prior commitment.

Entrapta had begged Adora and Catra to let her use Darla while looking after Finn because she wanted to see how it would react to the First Ones tech she had acquired. Adora and Catra were hesitant but Entrapta has assured them that things would be fine and that Finn would be perfectly safe so they relented but Finn was sure when they came to pick them up that they would be asking about every detail of what happened.

Right now in the castle of Dryl, Finn was acting as a lab assistant along with Wrong Hordak to Entrapta and Hordak, Finn was watching as Wrong Hordak was bringing devices inside Darla to connect it to her computer. Hordak was explaining to Finn what he and Entrapta had learned so far.

"So you think you found a time machine that the First Ones were working on?" Finn asked intrigued wearing their goggles as Entrapta had been on a console computer with Hordak nearby. Finn was thinking that with that then they could ace all of their future history homework.

"From what we could tell the First Ones found a way to look more into time powered by the magic on Etheria, the data we found suggested that it was abandoned because they decided the Heart of Etheria Project was a better more practical use of the planet's Magic." Hordak explained as from within the entrance Wrong Hordak came and gave them a thumbs up and his weird wink to signify that that it was set up in Darla's computer.

Entrapta then began setting it up to begin a test phrase as Wrong Hordak was about to walk out, however there was an electrical glitch in the computer and they started panicking when it looked like Darla was glitching out. "Wait... The glitch is interfering with the process and it is starting a pre emptive jump through time! So exciting!" Entrapta said with full excitement but Finn and Hordak looked more worried. Hordak was exclaiming that they were about a thousand steps behind any test runs and now they could lose Darla and Wrong Hordak right now with what could happen to them.

Wrong Hordak was caught by surprise and tripped down as he walking out, "Don't worry Uncle Wrong Hordak, I will come and get you..." Finn shouted running to Darla's ramp before Hordak could stop them.

They got in and was helping Wrong Hordak up and there was a flash of light, when the light cleared Hordak began asking Entrapta quickly if she was alright. "Don't worry, I'm fine. You should know as well as anyone that trial and error are what scientific discovery is all about. There is no need to worry and overreact..." Entrapta assured him before they both noticed that Darla had disappeared.

Entrapta's previous excitement was replaced by the same look of panic that her husband had, "No need to worry... We can fix it... We can use the tech to hone in where Darla was sent and bring Finn and Wrong Hordak back safe and sound..." Entrapta said with forced laughter as she went back to her computer's console.

"We had better fix it or we may have to face catastrophic consequences." Hordak exclaimed with Entrapta asking if he meant any damage done to the space time continuum with their experiment. "I was more referring to how Adora and Catra will react." Hordak warned and Entrapta now had a face filled with dread and terror, it was amusing to think how the two parents acted when their child just had a bruised knee from falling over in a nature trek but to think what they would do if they found out that their child was lost through time thanks to their experiment.

The servants came in and asked if they were alright and if they needed something, "Well just in case... You think you can get someone to help me make my will..." Entrapta muttered as she and Hordak then went hard on work looking through the notes they had collected so they could come up with a plan to fix this.
