Peabody's panic at seeing the missing WABAC was quelled by his remembering that there was a second option.

"Trusty Mach 2…" he sighed with relief as he hung a left on the walkway, only to have the path extend. It led him to a single, red door, which he swung open after inputting numbers on a computer panel and finding the wormhole with the most activity in question. "Paris, 1910… All right, then… Let's give you that test run we talked about, Mach 2. Let's hope you don't turn out like that apple did. I'd hate to try to reverse being turned inside-out…"

He thought he heard a crunch and a yowl as he slammed the door shut, but instead focused on rushing down the busy Paris streets, now wearing a dark suit jacket, vest, tie, and top hat, and with a cane in hand.

"Now where would they…?" he whispered, looking left and right. He flinched upon feeling something impact with the back of his skull, and reached down to find bits of a tomato staining his paws.

There stood Rigby, tail in hand, wearing a white and pink hat and a high-collared lace dress, and next to a vegetable stand, "If you broke this… You're sunk. And what's with this outfit?! What happened to me?!"

"You can't be here, you should really go back… Then I promise we will get to the bottom of this. The beams, the wiring, everything! You have my word," Rigby dug both back feet into the ground as Peabody attempted to make a push back towards the door. "Everything will be paid for, I assure you!"

"What are you?!" Rigby demanded, spinning around. "Right now I have more proof you're an alien than a dog!"

"I'm a father looking for his son," Peabody answered sharply. "And he's somewhere out here. I need to go find him and stop wasting time on this!"

Rigby stopped struggling. For a few feet, Peabody was even allowed to keep pushing. And then Rigby turned, and immediately started to scale up one of the brick buildings in the crowded Paris streets, dress and all.

"What are you doing?!" Peabody called out.

"Helping get a better look!" Rigby shouted back, followed by a "pardon" while scampering past the surprised woman seated at her balcony enjoying a cup of tea.

"Let's see… It couldn't be quite that far from our wormhole… Rigby, look to the west!"

"West…"

"No, no! that's your east! The sun's on the other side…"

"Got it! Hey! I think I might see them!"

"Are you certain?"

"The one has a pink cell phone! Is that a good enough hint?"

"Penny… All right, I'm going to go after them!"

"W-Wait for me!" Rigby struggled to follow after down the crowded street, finally latching on a few claws to the back of Peabody's coat.

It was too late. Already, they'd vanished again in the crowd. Peabody looked around, in a panic, and Rigby stood there, bent over, before sitting on the ground and panting.

"I… I think I'm dying…" Rigby huffed. "This corset's awful… Why would anyone do this to themselves?"

"Kitty!" Rigby heard an exclamation, and cringed while being lifted up by an unsuspecting girl on the streets.

"Young lady, please put down my friend this instant!" Peabody demanded as she started to walk down the street, Rigby in tow.

"Marie! Put down that fleabag!" scolded a woman holding onto the young girl's hand, presumably her mother. Without much hesitation, but a slight pout on her face, she unceremoniously dropped Rigby to the ground, and Peabody was there to help the cat back up on two feet.

"Why does everything think I—Ugh…. Little brat…"

"Now, now, she didn't know any better. Are you all right?"

"Yeah, fine," Rigby dusted off the skirt of the dress and grumbled, still holding onto one of Peabody's hands. Upon realizing this, Rigby broke their hold, adjusted the lace skirt, and then finally the tussled hat. "Where are we, anyway?"

"The heyday of Paris, in 1911. Approximately August, from the weather and the foliage."

"Nineteen… Wait…" Rigby looked down at the lacey dress, and back up to Peabody, "I've finally done it. I had too much catnip…"

"There will be more time to explain later, Rigby. For now we need to try to find the children… We had enough mess last year."

"I was in Mumbai last year, what happened?"

"Ohhh, nothing too large, just a rip in the space-time continuum."

"I thought daylight savings happened early this year… I really should get a computer or phone," Rigby continued to fidget with the corset, stopping briefly in front of a thick-glassed shop window. "So we're really… In the past? Hey! Can we go in the future, too? I… Hypothetically put a lot on the World Series this year."

"It's going to the Rangers."

"So you saw?"

"No. I'm a fan and hopeful."

Peabody stopped in front of the window, a clothing store with a suit and a dress, side-by-side in the display case.

"It's a pain and only should be used in extreme circumstances, I found…" he continued his walk, his head hung down a bit now, "I don't know why he doesn't listen, especially after everything."

"I didn't always listen to my mom growing up, either. I remember this one time we were in North Uganda… Long story short I got chased by this huge bird. She finally had to chase it off with a tree branch."

"So… Your mother, she was…?"

"Human, yeah. And she didn't raise me any different than she would've a human kid. Well, I guess she gave up on the baths, but—"

"I knew it! You did give me fleas!" Peabody snapped.

"You have no proof of that," Rigby returned while scratching the back of an ear with a back leg.

"…I thought cats were supposed to be clean…"

"I thought dogs were supposed to be able to sniff out things they were searching for," Rigby returned just as quickly.

"We're in Paris in a warm month… Highly improbable I'd be able to make anything out of all of this."

"Is that what that smell is?" Rigby wondered aloud, sniffing the air a bit.

"Why he can't just…" Peabody rose and looked about. After a moment, it clicked, as it always did in its natural fashion, "Wait. I've got it! Come on!"

Again he took Rigby by the hand and they were up again, the cat clutching the corset and bemoaning the run all along the way.

They finally stopped at the steps of a large marble museum. Rigby stopped running with such a quick halt that Peabody fell down onto the steps.

"This… This is…" Rigby gaped at the large structure, jaw open ever-so-slightly.

"The Louvre, yes… As much as I wish we had the time to look around, you win some, you Louvre some."

Rigby snorted a laugh after a moment of blanking, "Are… Are you sure they're in there?"

"Positive."

"Well, that'd… Give us some time to look around at least a little bit? Maybe?"

"…It's going to be a fast walk."

"You're such a parent…" Rigby muttered, now walking up the steps along with the dog companion. "At least the Mona Lisa."

"About that..."

"I don't care if it's still back in the present… Something about seeing it without that think panel of glass…"

"You certainly do know your art history. Where did you attend college, if you don't mind my asking?"

"I never went to school," Rigby shrugged. "My mom just taught me while we traveled. She went. I think she was afraid of what would happen if I went on my own… You know, little kitty in the big city?"

"Well, parents worry about these things…." Peabody said, clenching his cane just a bit.

"Plus, who would let a cat in school?"

"Well, I—Oh! There they are!" Peabody finally saw them in a break in the crowd, in front of a lot mural of a painting, Sherman's arms moving wildly as he explained a part of a painting to Penny. Peabody began his walk towards them, only to have this stopped by another paw.

"Just let them be for a second… It's kind of cute," Rigby said with a tilt of the head. "Look at them. It's like a little date."

"They're much too young for that…."

"Maybe, but it's still cute…"

Sherman nearly jumped out of his glasses upon turning around to see his father there. Mr. Peabody couldn't be held back by cat or even an act of God at that moment, and bounded for the boy after meeting eyes with him.

"M-Mr. Peabody! H-How'd you get here?!""

"It was my idea!" Penny exclaimed before Peabody could get a word in, jumping in front of Sherman just as quickly.

"That's fine—Your parents are going to find out about this as well anyway, Penny."

"What?" both children gasped.

"I promise it won't happen again, and I really mean it!" Sherman said.

"Plus we wanted to give you and your girlfriend space," Penny added, pointing over to dumbfounded cat. "You two were arguing like… Well… Cats and dogs."

Peabody balked, "My what?"

"Yeah, his what?! That's Mr. Ri—Ohhh…." Sherman's arm fell from where he'd been pointing at Rigby. Suddenly…. So much clicked. Including the dress, decked out in delicate lace. Certainly, he'd seen Mr. Peabody dress like this once or twice, on various adventures, but it never occurred to him…

"Sherman…. This is Ms. Rigby. Ms. Kimberly Rigby. The artist…" Peabody slapped his forehead and waved over to the cat. "Who is staying as a guest because her home was destroyed the other evening. During another joyride."

"Ehehe…" Sherman chuckled bashfully and shrunk a bit at this.

"We're headed home this instant. We're going to have a very, very lengthy discussion about this sort of thing."

"It's not the Trojan War or anything…. It's harmless, Mr. Peabody!"

"The Mona Lisa's been stolen!" gasped a man from the crowd suddenly.

"…August 22nd, 1911. One day after the Mona Lisa was stolen, people finally realized that it was simply lifted away… We never really notice these things until they're gone. The culprit took off that way!" Peabody shouted, turning and pointing in the direction of the country of Italy. This resulted in two guards taking off running, and Peabody adding, "All right, we're off."

Rigby looked back at the disappointed children as they walked out, the four together, two by two. She then took hold of Peabody's arm, much more gently than in times past, and cleared her throat, "Could we get something to eat, first? I… Think that time travel made my blood sugar low."

"Well, we can't have that… All right. We'll get something and then we're headed home."

Rigby winked at the two along the way, and linked an arm with the genius at her side, as many of the women down the street did with the women next to them.

"…Are you sure they're not dating?" Penny asked.

"Ew, gross! They've known each other for only a couple of days! And I think they hate each other. More than a little bit."

As he spoke, he grew aware that the two animals in front of him were in their own world… Some talk about Mayan culture and pottery. He noticed the tail of his father, wagging ever so slightly.

"Uh. Huh," Penny nodded sharply, and Sherman gulped.

The eyes of both children went wide as desserts were carted over on a silver tray, and these were added with excited smiles as come small cakes were laid out in front of them.

Rigby looked at her own, a small tray of cookies she'd been served on a platter, shrugged, and chose to dip these in tea, crunching them loudly.

"Not a bad ganache," Peabody attempted to ignore the crunching as calmly as possible by focusing on his cake, and by clearing his throat and adjusting his glasses as he glanced up to his son. "Sherman, I understand your wanting to go off and have fun, but doing this after such a short time after the last incident is unacceptable. I'm going to have to think long and hard about your renewal to the Audubon society."

The boy gave a moan, "B-But Mr. Peabody—"

"No buts. And no giggling about "buts," either. You're going to have to learn that time travel is incredibly serious, and not to be abused. I—" he noticed Rigby yet again cleaning her mouth by licking her paw. "Please refrain from doing that at the table. It's a bad example."

"So are you gonna be living with them long?" Penny asked, her voice lowering as she leaned in to the cat.

"Unless I find a hotel. I'm gonna try to make the best of it. Accidents happen to everyone, after all," Rigby muttered, setting both of her paws at the table.

"Not to everyone," Peabody sighed.

"What if you accidentally find a dollar on the street? That happens to everyone."

"Then you happen to find a dollar on the street. That's a coincidence. And it's statistically impossible that that would happen to everyone."

"But it's a happy accident that you looked down to find it."

"And that's a coincidence you happened to look down and find it."

"…If you replaced this with talking about who paid the car insurance, this would be my parents," Penny muttered, watching the discussion continue go back and forth between the two.

"Then what about irony?" Rigby interjected.

"We weren't even… Our destroying your building was an accident. It was a coincidence that there happened to be an intelligent cat in there and it was struck by an intelligent dog. It's an irony that a cat and dog are sitting together having a civil discussion."

"Are we? I hadn't noticed."

"This is worse than setting my thesis advisor straight," Peabody said with a rub of the temples.

Rigby stood up from her seat, and without a word walked out of the restaurant.

"Um. Mr. Peabody…? What happened?"

"I… I'm not sure, Sherman?" the dog answered, seemingly not believing his own words. "Excuse me, children."

"….Did I really just hear that?" Sherman whispered as Peabody walked out of the restaurant, after the cat.

"Even better, I just got that on video," Penny answered, holding up her cell phone.

"Ahem…" Rigby glanced up to the outstretched hand as she sat alone on the curb of the now quiet sidewalk. "We're running out of feet to get started badly on, you realize."

"Still have two more..." Rigby muttered. "I'm sorry. I shouldn't have stormed out. Not in front of your kid."

"Nothing's perfect. I've learned that…. With great difficulty and kicking and screaming along the way, I might add," he helped her to rise from the sidewalk and walked with her back down the sidewalk.

"I lied when I said I didn't know who you were… I… I mean, of course everyone's heard of you. I think I was just a little… Intimidated?" she laughed. "I know that's ridiculous. And I guess I just feel like an idiot, and the harder I try to keep up the worse it gets."

"Out of the contrary, it's completely understandable," after a pause, though, he cleared his throat. "As is often the case when meeting someone new. Having an illustrious artist such as yourself in our presence is equal cause for trepidation. But… If you wanted to stay for a bit while the repairs are made, that will dissipate."

"In all honesty, I don't understand half of what you say, but I understood the "stay" part… And I don't think I've got much of an option, at this point," she chuckled, waving as they saw Sherman and Penny waiting outside.

"…This is so gross…" Sherman muttered, shuddering.

"I made sure the door was locked on the Mach 2, so we should be fine to all fly back together."

It was only when they were all seated in the WABAC and halfway back home that there was the realization that no one had paid the tab on at the restaurant.

"I'll have to go back on to tomorrow tomorrow and leave the bill… And an apology," said Mr. Peabody, clearing his throat.
