King Maximilian was laying lying on his bed really sick

Alicia: Are you certain this will work, Doctor Quack?

Doctor Quack: You're just going to have to trust me

Serena connected a chaos emerald to a machine

Chuck: How's the focusing chamber?

Serena: Almost ready... Okay it's ready!

Doctor Quack: Between my plans, Sir Charles experience with strange mechanical means and Serena's genius this should go fine.

Sonic: Should-?

Doctor Quack: Throw the switch, Chuck!

Chuck pulled the switch and there was a bright light. Then Maximilian started to slowly wake up

Maximilian: A-Alicia?

Alicia held his hand

Alicia: I-I'm here Max!

Doctor Quack: Welcome back your highness!

Maximilian: How...

Doctor Quack: A miracle of science and magic, Sir. You see with the chaos emerald-

Serena: We'll explain all that later.

Doctor Quack: Right! Of course.

Maximilian: How... Stands the kingdom?

Elias: Knothole stand strong, Father.

Maximilian: Elias... My boy... As king?

Sally: That's right, Dad.

Maximilian: And You my little bean?

Sally: I-I'm with freedom HQ now

Maximilian: Where?

Sally: Our old renovated headquarters. It's where we're fighting from now

Sonic and Serena walked outside to give them some privacy

Sonic: Nice work in there, Cuz!

Serena: I'm just glad it worked.

Then Sally ran up to them holding the chaos emerald

Sally: Hold on! I'm sorry guys! I almost forgot your uncle wanted you to have the emerald now that my dad is okay

Sonic held the emerald

Sonic: Thanks, Sal!

Sally: Consider this as my thank you

Serena: You're welcome. It's what we do

Sally walked back into her father's room to see him

Sonic: That reminds me! We have Tails and his uncle!

Serena: Now? But-

Sonic suddenly grabbed Serena and ran off

_____________________________________

They both stopped right in front of Tails and his uncle Merlin

Serena: I ask you this all the time. Can I have a warning before you do that?

Sonic: Sorry! Force of habit!

Tails: Hey Sonic! Hey Serena!

Sonic: Hey Tails!

Serena looked at Merlin

Serena: Sonic mentioned you wanted to see us?

Merlin: Patience, young ones. This old charlatan has one more trick up his sleeve. Namely I'm going to make Serena's parents reappear

Serena stood there shocked

Serena: ...Wait... WHAT?! T-They're still alive?!

She started pacing back and forth

Serena: I thought they were missing for years! I even started to wonder if they were both dead! And you're telling me this now? Why now?! I don't-

Sonic comforted his cousin

Sonic: Hey don't worry, Cuz. Just breathe.

Serena took a deep breath in and out then looked at Merlin

Serena: How are we bringing them back?

Merlin: All we need is something to open a path to the ring of Argentum and something to power such an incredible journey.

Serena: Which is what the chaos emerald is for. Since Shadow uses chaos control to teleport.

Merlin: Exactly, Serena. Now reach out with your heart and find them. I will help keep us intact

Sonic: I wish I knew where my girl Fiona was. She might've enjoyed this.

Serena: Sonic. I don't hate Fiona but this is a family situation.

Sonic: Yeah I get it.

Suddenly Sonic, Tails, Merlin and Serena disappeared

_____________________________________

Then the four of them opened their eyes and were now in another dimension

Sonic: Holy... This is not how I left the place!

Serena: You'll explain that later. I'm going find my parents!

She ran off before Sonic could say anything

Sonic: Serena! Wait!

He was about to go after her when he saw some rundown spaceships

Sonic: Merlin do you recognize these spaceships?

Merlin also looked around

Merlin: Hmm... The Xorda

At that moment two hedgehogs that looked a little older than Sonic walked up to him.

Serena's father David

And her mother Martha

Martha: Hello Sonic. It's good to see you after so long

Sonic: Aunt Martha! Uncle David! Uh... Did you get younger?

David: We're frozen in-

Sonic: Wait! Actually hold that thought!

He ran off and then came back with Serena

Sonic: Here! Now you can finish!

Serena: Sonic... Again! Give me a warning-!

She saw her parents standing there

Martha: My little girl...

Serena: Mom!! Dad!!

She immediately jumped into their arms and hugged them

Serena: I missed you so much! But I-I don't understand... You're just a little older then I am...

David: We have been stuck in the dimension for years frozen in time. So even after about 18 years we're still the same age from the moment we got here

Serena just hugged them both again

Serena: I don't care... You're still my parents!

Then both David and Martha noticed Serena's robot limbs

Martha: How did...

Serena: Oh... I was caught once but I was lucky to get a chance to stop it before it was too late! Just like what you said I'm still the same!

David: I never doubted that for a moment, Serena.

Sonic was watching trying not to cry and Merlin put a hand on his shoulder

Merlin: Are you all ready to go?

Martha: Yes...

At that moment they all disappeared again

_____________________________________

Later that day David and Martha arrived at the castle to see the royal family

Elias: David! Martha! It's so good to have you back! On behalf of the Kingdom of Knothole I welcome you both home! And you literally haven't changed!

David seemed a little annoyed at that last part

David: It's great to be back but we've still changed mentally.

Elias: I completely understand that It'll take time to adjust.

David: Thank you but I doubt it'll take long

Martha: What has changed is Knothole itself. After all you are king now, Elias.

Elias: Yes and remember we're here to help with whatever you need. After all your daughter and nephew have helped us more times then I can count

David: Thank you again, Elias.

Elias: Will either of you consider in joining my court of Acorn and build an even better Knothole?

Elias held out his hand and David shook it

David: There's nothing to consider, your majesty. Our time away has given me many ideas on how to improve the kingdom I wish to share with you soon.
