"So there's a working time machine in the museum?" Felicia asked of Beatrice as the two teenagers entered the Danville museum, as they made their way to the 'Gadgets of the Ages' hall. Beatrice caught sight of her aunt Candace, Grandma Linda, cousins Amanda, Xavier, and Fred... along with twenty-year younger versions of her parents, and Ferb and Candace using the time machine.

"What the…?" Beatrice said in surprise.

"Yeah... I had no idea your parents were, THAT adorable. I mean I've seen the old pictures, but that just doesn't do it justice!" Felicia said, Beatrice simply rolled her eyes as she confronted her aunt.

"Aunt Candace? You mind explaining why there were young doppelgangers of you, mom, dad, and uncle Ferb?" Beatrice said sternly.

"Beatrice! I... well it started with a tool that can fuse metal and wood at a molecular level-"

Candance then went on to ramble about the events in question, specifically of how she created a future where Heinz Doofenshmirtz. (Whose name she forgot in all the confusion) had subjugated mankind after she had busted Phineas and Ferb over the roller-coaster on the first day of summer. "I see... and is the time machine in question still around?" Beatrice asked.

"Yeah, yeah it's still on display. It should still work." Candace said, pointing to the machine created by Xavier Onassis, which according to her aunt, he created to get corn-dogs.

"Well, then there's only one thing for me to do now," Beatrice said as she donned her goggles, looking over the components of the time machine.

"Wait... Bea, what's going through that head of yours?" Felicia asked in concern.

"So did Phineas also make Beatrice?" Linda asked.

"Yep, he built a whole machine in the basement just to make her," Candace said.

"Really? And all this time I thought she was adopted." Linda admitted.

"Components analyzed categorized... and ready to be disposed of, and grandma, how... where would you even adopt a sentient android?" Beatrice said, Linda merely shrugged.

"I only knew you were a robot- ANDROID I MEANT ANDROID!" Linda said.

"It's quite alright grandma. I'm just going to eat parts of this time machine." Beatrice said as she opened a compartment on the time machine. Removed several parts inside and ate them.

"Mom, Beatrice is acting weird again!" Amanda said.

"It's for the good of the time-stream Amanda! Literally, anyone could use this thing a screw up the time-stream, and wreak unimaginable chaos. So I'm going to make sure no one can use this thing for any inter-temporal shenanigans." Beatrice said as she removed the purple light-bulb on top of the machine.

"But can't your nano-bots assimilate what you eat?! And take on some of its traits?" Candace said as Beatrice had swallowed the parts.

"...oh... I probably should have taken that into account- OW!" Beatrice shouted as she clutched at her stomach. In turn, she started to glow in various colors.

"I... I can see through time... why are there so many clocks?" Beatrice said deliriously.

"Beatrice, stay with us here!" Candace said in worry as she laid her robotic niece in her lap.

"I'm not dying Aunt Candace... I just feel really, REALLY, sick, and-" Beatrice was then cut off as she loudly farted a purple cloud.

"And some people say museums are boring," Felicia said glibly.

"Most... no, ALL museums don't have robots getting sick from eating time machine parts!" Amanda said.

"And I'm jotting that one down," Felicia said as she took out a pen and notepad, and wrote down what Amanda just said.

"Huh... someone get me a bucket... a metal one. Plastic tastes... well like plastic." Beatrice said groggily.

"And writing that one down as well," Felicia said as she wrote down Beatrice's words.

"Do you really keep a log of strange sentences?" Linda asked, Felicia merely nodded happily.

Eventually, Beatrice was brought back home. With Isabella tending to her as best she could. "Why didn't you ever tell me you went time traveling?" Beatrice asked, looking exhausted.

"Your father and I DID. In fact, I stopped that whole mess from coming about by going back in time to before Phineas and Ferb needed a wood and steel tool. I mean if you can see through time, you should know that." Isabella said as she rubbed Beatrice's forehead with a cloth.

"Mom, everything is a disjointed mess of events out of order... so that's why they built Stone Henge, kind of... kind of underwhelming. I mean, they won't not have nearly not-not enough voles to make the bagpipes..." Beatrice said.

"Well I called Phineas, and he should be back from Switzerland soon," Isabella said.

"Can I get an ETA on that?" Beatrice asked.

"He said that the meeting was too important to just up and leave. For now, just get some rest." Isabella said as she left the basement.

"Well... I'd say it's nice to be sick, but unlike the few times with the flu. This... this isn't even mildly interesting to experience, even if it's temporally based." Beatrice mumbled to herself. Several hours passed as she stared at the ceiling in an almost trance-like state. Foaming at the mouth with purple film seeping out. "Darn it... this is how I'm going to die isn't it…? Foaming at the mouth, seeing the entire history of the universe as... some kind of horribly confusing montage of overlapping footage that does not make any kind of sense, even with the possibility of hindsight." Beatrice gurgled.

Then in a flash, the Errant Travelers Tach'noma materialized in the room. "I'm no doctor... or even a robotics engineer. But I can help you." The Errant Traveler said as she stepped out of the Tach'noma.

"Short answer ET," Beatrice said groggily. "I ate some parts from a time machine so that-"

"Nobody could use it, and accidentally screw up the time-stream. Yes I know, I was on my way to fix the mess your aunt caused but... well you told me that you were sick." The Errant Traveler said as he used his wrench-wand device over her.

"Do you know what's happening to me?" Beatrice asked.

"Short answer, you've splintered your future. Meaning that... well, you're going to have run-ins with potential future you's." The Errant Traveler said.

"Meaning...? what does that even mean?" Beatrice asked groggily.

"It means that because you ate those time machine parts. You now have limited control over your personal timeline. You can stop time for yourself for brief periods, and move about freely. But as another consequence, your future has diverged drastically." The Errant Traveler said.

"How bad... how bad we talking about?" Beatrice asked as she slowly got better.

"Bad enough that, when you met up with you, you were being chased by a future you, one that… apparently had her emotions completely disabled or something like that." The Errant Traveler said. Then without any warning, a gynoid woman stepped out of a temporal rift.

"And there she is again!" The Errant Traveler said in resignation. The women did indeed look like an older version of Beatrice.

"Errant Traveler, I have come to protect myself." The future Beatrice said.

"Well I can protect myself," Beatrice said as she wobbly stood up.

"You know not what he is, or what he is truly capable of." The future Beatrice said.

"I lost my first friends for ten years because of him... and also got them back thanks to him. So unless you actually know something I don't know. Please... get lost!" Beatrice said in annoyance.

"No. I know that he has done you a service. But you are blinded by your emotions. I will make certain that you will see him as the monster that he is!" The future Beatrice said.

"Hey! I'm not perfect, but I'm not a monster...! that depends on people who have met me and known me! But you, I haven't actually met you for the first time! Or is that the other way around? Point is, what right do you have to judge me?" The Errant Traveler said indigently.

"So we have encountered each other out of chronological order?" The future Beatrice said.

"Yes, believe me when I say that I HATE IT when I meet people out of order! It's just so confusing, and then there's the risk of accidentally telling someone too much or too little, risking the entire time-stream on an ill-placed word or piece of information!" The Errant Traveler ranted.

"Is anyone going to do anything, or are you going to posture like bad anime villains!?" Beatrice said in annoyance.

"Very well then." The future Beatrice said. Then, while the future Beatrice stood still, perfectly still. The Errant Traveler was punched into a wall

Beatrice (our Beatrice not the future one) donned her goggles and turned one of her arms into a sword, and attacked the future Beatrice. Or rather tried to, but she kept dodging her strikes. "You waste your energy defending him. You cannot possibly hope to win." The future Beatrice said.

"Oh... I might surprise you, Cricket?" Beatrice said.

"You wish to test the chrono-displacement?" Cricket asked, Beatrice simply nodded, and Beatrice then transferred into a monochrome world.

"Trippy," Beatrice said as she marveled at frozen dust particles hanging in space, future Beatrice became colored.

"Did you not think that I would remember this?" The future Beatrice said.

"I'll be honest, I didn't even care!" Beatrice said as she engaged her future self. The two fought up and down the house, blinking randomly in and out of time. Beatrice tried to minimize the damage her future self was doing to the house. "What are you even doing here?!" Beatrice asked as she deflected blows from her future self.

"To ensure your survival, and by extension mine." The future Beatrice said.

"Well aside from eating some time machine parts and getting sick. I'm fine, so, please. Turn around, and don't come back unless you have some help to offer me." Beatrice said.

"I see... your logic is sound. I am sorry, but my memories. They are... they are fractured and disorganized. My main desire for returning to this time is to rediscover what I have forgotten or miss-remembered." The future Beatrice said as she turned her arms back to normal hands.

"What... that's it? You came back in time... to remember?" Beatrice said in confusion.

"Yes. While my intention was not to fight you, I was trying to protect you from the Errant Traveler." The future Beatrice said.

"No... No, he helped me, helped me from... well the side-effects of keeping people from screwing around with the time-stream as bad as Aunt Candace did." Beatrice said.

"He does provide help." The future Beatrice said. "But make no mistake... he is as dangerous as he is generally eccentric and silly. He will lead you to dangerous places-"

"Yeah, I've already been to such places. Or do you also not remember some of... our, inter-temporal adventures with him? Like that one time, we took our friends to that dimensionally transcendental zoo on T'har III? The worse thing that happened was Mathew getting into the Penguin habitat, the guy was lucky not to freeze." Beatrice asked.

"... We shall meet again." Future Beatrice said as she disappeared in a temporal rift.

"Beatrice... why are you okay, and what has been going on?" Isabella asked in concern.

"A future me came by, punched the Errant Traveler into a wall. Then went on about she was trying to protect me. Then we had a sword fight blinking in and out of linear time. Then I told her that the Traveler cured me of the... time travel parts snack. Then she left... it was honestly a whole thing." Beatrice explained.

"I don't think I got a chance to see her," Isabella said.

"Well, you might get another chance. Apparently, because of the Errant Traveler healing my illness, I now not only have limited time travel. Well more like time STOPPING. But she could travel back in time at will and was convinced that the Errant Traveler was bad. She never actually said what specifically... the point is. Apparently, I'll be meeting her again, and tell the Errant Traveler about my sickness so that he can cure me." Beatrice said.

"That... sounds really confusing," Isabella said.

"Welcome to my world mom. Now if you'll excuse me, I've been sick for most of the day, AND just ended a sword fight with myself. So I'm going to grab a bite." Beatrice said as she waltzed towards the kitchen to fix herself some lunch.
