In a lab inside the Multiverse Initiative's compound...

Star used her six hand's fingers to press buttons on a panel, with Sonic and Pearl standing at her sides. Giana was already in her protective suit, in front of the open back of her van, which showed the entrance to the Dream Tunnel.

"Okay, here it goes!", Star announced. "Giana, you can now fire the...uh, weird van stuff."

"The breakers and emergency generators are ready.", Sonic informed.

"Nice! 'Cause...well, I don't wanna lose gal in the 50's."

"Excuse me?", Giana asked, with a horrified face.

"She's just joking!", Pearl said in a mildly hysterical tone, before whispering on the Mewman's ear, "You can't stay things like that!"

"I was...just jokin' real bad.", Star protested.

"You're kidding, right?"

"I don't know; we are talking about travelling in time with dreams! Either it's a big joke, or a big shock. Ok, now we're good! Giana, wear the helmet. I'm gonna send you back in a week, and you'll walk in it for a hour before bringing you back. How does that sound?"

"Not confusing at all.", Giana lied.

"Giana, you got this. Good luck.", Sonic affirmed.

"I sure do, Sonic. I sure do."

Star began to count down from three, before pressing a button. At first, for five seconds, nothing happened, making the Mewman girl get worried enough to press another button, pulling back Giana...who de-aged back to the early tween age she had back on her first adventure.

"Guys?...I, don't feel right. At all.", the younger Giana said.

"What the hell?", Sonic said, confused.

"What is happening?", Star said, even more confused.

"Who is...her?", Pearl asked, nearly refusing to believe it was the same person sent through the tunnel.

"Give me a sec.", Star said, using her arms to press more buttons.

"Is that you, Giana?", Pearl fearfully asked.

"Yeah, that's me!", the younger Giana said, before getting sucked back to the Dream Tunnel and replaced by, this time, a old woman in the protection suit of Giana.

"What the...", Sonic said.

"Hey, I need a little space here.", Star said, most of her arms getting too crampled.

"Can you bring her back?"

"I am trying!", Star stated, messing with the panel in a attempt to bring the original Giana back.

Once the old Giana got sucked into the Dream Tunnel, a baby girl in Giana's protective suit appeared.

"Giana?", Star mouthed, almost in disbelief.

"It's her. As a freakin' baby!", Sonic, nearly annoyed, pointed out. "Bring the normal Giana back."

"Pearl? When I say kill the power, shut it down."

"Oh my god...", Pearl mouthed, slowly bringing one of her hands to a lever.

"Aaaand- NOW! KILL THE POWER!"

When Pearl pulled out a lever, the van's power shutted down, pulling the normal Giana back to the trio, and she looked pretty dazzed and dizzy at the same time. "Somebody peed my pants...and I don't know if it was baby-me, old-me or...just myself.", she stated once her head fully got back in place.

"...time travel!", Star cheered, extending her three pairs of arms to the sides in a dramatic way. Sonic's response was only to shake his head and walk away from the room. "Hey, what's up? That's obviously a victory!"

But for Sonic, it really meant more and more defeat. He sitted thoughtfully outside the Multiverse Initiative's compound, saddened the only chance the group possibly had of victory was gone...before hearing a whoosing noise, high in the sky. The hedgehog cranked his neck up to find, for his surprise, his best frenemy NiGHTS flying down, the rain of cyan dust that came out of her hands raining at him, like snow.

"Why the sad face?", NiGHTS asked. "Let me see...Giana became a baby."

"For a while, sure.", Sonic replied. "But, what are you doing here?"

"That's a EPR paradox.", NiGHTS spoke, not really caring for the blue hedgehog's question. "You almost pushed time through Giana, instead of the intended of pushing Giana through time. It's dangerous; somebody should've warned you about that."

"You did..."

"Really? Thank godness I'm here, then! But anyway, I fixed it.", NiGHTS stated, before warping a device on her hand. "A Time-Space GPS in full working condition! And, I just want freedom and peace...but it turns out I hate how hiding feelings is rotting."

"Yeah, me too."

"We have a shot at getting the stones, but first, let me tell you about my priorities. Bring back what we lost? Of course, I have hope! Keep what me and they gained? At every cost. And...not dying will be nice."

"Sounds like a deal.", Sonic pointed, as he and the Nightmaren shared a handshake.

For the hedgehog's surprise, however, NiGHTS made a vortex with her cyan dust and pulled something out of it...Sonic's speed shoes. And extended her hands to give the shiny, red, gold and white shoes to him.

"I dunno, NiGHTS...", Sonic hesitated.

"Why? They made it for you. Plus, Zoe would probably toy with it before I could give it back to you, and disasters would happen."

"...Thank you, NiGHTS.", Sonic said, picking the pair of shoes by their shoelaces.

"Can you keep it more quiet? I couldn't get stuff for the whole team.", NiGHTS softly said, hesitating to continue speaking. "...We are getting all of them, right?"

"Actually, we're gonna work on that."

…

In the yard of the compound, the Amazon's ship landed in, interrupting a Giana sitting in a bench before she could have a bite out of a bombolone. Frisk and the remaining members of the Amazons of the Galaxy walked out of the ship.

"Hey, where is Big Butterfly?", Coraline asked, taking Cornet's hand.

"Well...in the kitchen.", Giana replied.

"Pines, Northwest? Careful on re-entry.", Frisk warned through a earpiece. "Someone is just eating their food on the landing zone."

Right in the time Giana was recovering her senses, the War Trio landed in front of her without a explict warning, shocking her enough for her to drop the whole bombolone. "Oh my gosh!", she cried.

"Heyo!", Mabel greeted cheerfully. Dipper and Pacifica just waved as the trio walked away.

Star Butterfly, coming out of the compound and realizing at Giana just lost her lunch, decided to give her a plate of nachos, just like how her friend Marco Diaz used to do. Giana was a bit puzzled over the act of kindness of the Mewman, but accepted it anyway.
