A/N: I am so sorry for not updating sooner, but I've been real busy and fanfiction hasn't been my BIGGEST priority. Oh well, anyway, I hope this chapter will be enough till the next one.

Disclaimer: I do not own Phineas and Ferb which are owned by Dan and Swampy, or Phillip Flynn and The Shadow which are owned by TheCartoonFanatic01. I do however own Marissa Flynn.

Inside The Shadow's subconscious during the confrontation with Ferb and Isabella

Medieval Phineas ran outside to the woods. It wasn't raining anymore thank goodness. He ran into the woods and sat on a large rock.

"He's just so full of himself," he said.

He looked on toward Malifishmirtz's fortress. It crossed his mind that he's a wizardling. He read about some wizardlings that didn't always use their powers for good...That was the nice thing about being a wizardLING because you could choose to use your powers for good or evil until you were a wizard. He wondered if maybe he should talk to Malifishmirtz about training him in the ways of dark magic. Dark magic was tricky and hard to control, but he's strong enough. Sure he never used his magic except to make potions, but that's because he didn't want to show off. Now he wanted to show Ferbalot, to show Candivere and Marivere, to show Isabel and everyone else...to show everyone JUST what this small little wizardling is capable of. He felt dark energy, dark emotions well up inside him as he made his way to Malifishmirtz's fortress. He knew Malifishmirtz had broken away during the Midsummer Wode-Gathering Harvest Bonfire's Eve. He made his way to the fortress, and it didn't take long. It took about as long as it did when he, Ferbalot, Baljeetolas, Bufavolous, Isabel and Marivere traveled there too. He got past the troll woman easily. He used his wizardling powers to levitate across the Rocky, Shallow River of Nevermore, and he had a semi positive attitude as he crossed the Swamp of Spit-poor Attitude. He skipped the Cave of Ten Thousand Monsters because he wasn't going for Excaliferb. Lighting struck as he approached Malifishmirtz's fortress. He knocked on the door, and suddenly there was a trapdoor. The wizardling yelped as he fell down a tunnel and into a cage.

"Ah Parable the Dragonpu-...Wait you're not Parable the Dragonpus. You're that little kid that had all those potions," Malifishmirtz said.

"Yeah, so what?" Medieval Phineas snapped.

"Uh, sorry about that. I was expecting Parable the Dragonpus," Malifishmirtz said as he lifted the cage imprisoning the young wizardling, "Sorry about that."

"Yeah well it's just me," Medieval Phineas snapped again.

"Geez kid. I said I was sorry. Let it go," Malifishmirtz snapped, "What are you doing here anyway?"

"I wish to learn the ways of a dark wizard..."

"Let me go Major Monogram!" Carl yelled from his new stronger cage. It wasn't as strong as the cell Marissa was trapped in.

"Master Phineas wants to keep you locked up until he wakes," Monogram replied.

"Major Monogram, listen to yourself! You're not supposed to be under that maniac's rule. You're supposed to be in charge of the O.W.C.A," Carl reasoned, but Monogram just stood there like a robot.

"Just give it up. He's obviously not going to listen to you," Marissa said from inside her cell and sighed, "I hope Candace and the others got away with the locket."

At this, Monogram turned his attention to Marissa. He turned on a camera that Phineas had given him for security purposes, and it caught every word of what will next be said:

"Yeah, that locket's important. If it fell into The Shadow's hands, that wouldn't be good. At least that's what I've heard from you and the others. Why do you think The Shadow wants to keep you around? It feels like of all his prisoners, besides Phineas himself, you're one of his most important," Carl said.

"I...I don't know. All I know is that the first time I envisioned meeting Phineas...I didn't imagine that he'd be under the control of The Shadow...it just...I thought I could handle it...but I just couldn't. I just hope they can figure out how to work the locket and save my little brother. Who knows what that spirit is putting him through?"

Phineas watched in horror. He didn't want to think that THIS was truly who The Shadow was...or used to be. He looked at Marivere who just watched.

"Marivere," Phineas asked and she turned her head, "Is...is this truly how The Shadow came to be?"

"Yes," Marivere said sadly, "sadly yes, but you'll never understand it unless you watch all of it."

Phineas nodded, and he watched the memory more...

"You wish to learn the ways of a dark wizard? How do I know it's not a trap?" Malifishmirtz sneered at the boy.

"Because it's not! I want...I want revenge," Medieval Phineas said startling Phineas.

"What? What do YOU want revenge for?"

"That's none of your business. Just teach me or else!" Medieval Phineas shouted and already darkness could be seen in his eyes. Malifishmirtz smirked.

"Yes, that's definitely what I was looking for. You are worthy of the dark magic."

Instantly Medieval Phineas smirked evilly. Days passed and the wizardling got stronger. He was able to levitate, throw shadow balls and other dark attacks, and his eyes changed color. It was something that came with seducing to dark magic. Medieval Phineas destroyed the last of his training dummies that looked like Ferbalot, and he smirked at his master. Little did Malifishmirtz know that Medieval Phineas' power had grown stronger than his master. The dark magic really corrupted his mind, and he turned on his master.

"Very good Phineas. Now together we can take over not just the Tri-Kingdom Area, but we can take over the whole world!" Malifishmirtz cackled.

"I do not need YOU to take over the world," Medieval Phineas said.

"What? But I'm your master! You obey me!"

"I DID, but now you are of no use to me," Medieval Phineas said, and he picked up Malifishmirtz with dark telekinetic energy, "I admit. You were useful when I needed to learn the ways of dark magic, but now that my powers have exceeded yours, I can dispose of you."

With that, Medieval Phineas sent a blast at blast was exceedingly powerful...powerful enough to destroy the sorcerer. Medieval Phineas smirked evilly as he summoned dark shadows to obsure his figure, for his new target was Ferbalot...
