For this part of the story, just pick the outfit you like for Ash the best (region wise). I didn't have one in mind so go ahead and paint a picture!

Delia woke up on the couch in the living room. The last she remembered her son told her he was pregnant. It was just a joke right?

"Mom? Are you ok?" Ash asked as she opened her eyes.
"I'm fine, but are you serious about being pregnant?" she said.
"Yes."
"But you're only 16!" she said.
"Mom!"

They were about to quarrel when Misty butted in.

"It doesn't matter the age right now!" she yelled, "All that matters is that we have these kids to raise soon!"

"I guess you're right," they both said.
"Now Ash," Misty said, "Go get dressed, we're going to a doctor in Viridian."
"Alright," he said going to his room to get dressed.

Meanwhile, Mr. Mime was busy putting away groceries and making sandwiches. Not paying attention to what was going on.

"Misty can you change it to the news?" Delia asked.
"Sure Delia," Misty said with a smile, trying to lighten the mood more.

She flipped it to the PNN station (Pokémon News Network) on channel 202.

"In other news, Johto has been completely conquered by Team Rocket. Many fear that Kanto is next. Lt. Surge, the Vermillion City Gym Leader, is planning for a counter attack…." The harried reporter said into the camera.

Misty was in shock but didn't show it. What was this? Wouldn't she have known this sooner? Then Delia broke the silence.

"I'm not sure if I believe this multi-worlds theory," she said, "What do you think Misty?"

Misty shook her head and turned to Delia. Then her attention turned back to the TV. But instead of the other broadcast she saw one on the theory of possible multi-worlds, or parallel universes.

Misty then said to her, "Yeah I think this sounds convincing."
"Well I still need some then," she shrugged.

Misty was still sitting there in shock when Ash came out dressed in his normal clothes and said, "Are you ready Misty?"

"Yeah I am," she said walking towards him.

They were about to leave when Mr. Mime came running up to them with a picnic basket.

"Mr. Mime!" the pokémon said excitedly.
"Thanks Mr. Mime," Ash said.
"Pikapi!" the electric pokémon said as he came running up to the couple.
Misty looked at the pokémon and smiled, "You can come too Pikachu."
"Pikachu!" the pokémon said excitedly.

They finally started to head off and Delia and Mr. Mime waved them goodbye. The time was 10:35 once they left.

The group had made great progress; they were half-way to Viridian City so they decided to take a lunch break which consisted of sandwiches and some drinks. Plus there was some pokémon food for Pikachu. Once they were done they set off for Viridian once again.

They reached Viridian at 12:45 by the time on Misty's watch. Pretty good timing Misty thought. They first went to the Pokémon Center to leave Pikachu and the other pokémon with Nurse Joy. Next, the duo went to the doctor's office. They were able to walk right in and see the doctor since there weren't any other patients waiting.

Both their jaw's dropped when the saw the doctor. Both exclaimed, "Marilyn Monroe!?"

The woman turned around and pushed down her white dress, as she was on top of an air vent. She then walked off the vent, took off the wig to reveal long brown hair underneath.

"Sorry guys I'm not her," she said with a smile, "I'm the doctor. My name's Hannah Hartland, nice to meet you."

She shook both of their hands then went back to talking.

"I was just working on my costume for an upcoming production," she said, "It's for the theater. So now that's out of the way, why don't you get up on the table Miss."

She motioned for Misty to get up onto the examination table.

"Uh, this isn't for me," she said, "It's for him."
She pointed to the blushing raven-haired boy.

"Um, is this a joke?" she said shocked.
"I don't think so," Ash said.
"Then hop up onto the table and roll up your shirt and jacket,"

Ash did what he was instructed to do. Misty took a seat on the chair next to the table. The doctor then came back with a screen with ultrasound equipment. She then rubbed some gel on Ash's stomach and moved the wand over it.

"Ah ha! See that?" She said pointing to the pea sized shaped dot.
"That's my baby?" Ash said in awe.
"So it's true then," Misty said.
"Well this is sort of a medical mystery how this happened but it did," Hannah said, "But you somehow have a womb capable of sustaining new life."
"I guess so," he replied.
"So now the boring, but important part of the visit," Hannah said.

She went over what was considered "good" and "bad" foods for Ash to eat during this pregnancy. She also said that he'd need maternity clothes around the fourth/fifth month mark or whenever his clothes started to become too tight. They then scheduled another appointment for the second/third month mark.

After a half-hour visit, Ash and Misty picked up there pokémon from the Center and were making their way back to Pallet…

Ash will have definite clothes soon! I'll be specific next time and once he gets bigger I'll describe the clothes he has on for the day.

Ciao!
