"Finally!" Gaster yelled in excitement. "I've made it out of that stinking void!"
Gaster ran to the castle where Asgore would be, but Gaster was stopped by the royal guards. One that looked a younger Undyne. Smaller, cuter and Alphys like glasses. Alphys and Undyne's child?

"Hey Punk! You are you here for?" The child looked up at Gaster.

"Uhhh..." Gaster was stunned that a small child would be in the royal guard. "What's your name subject 0063952157785?"

"Did you just call me subject? Mom! Ma!" The child called.
Not long after Undyne came running out. Once Alphys came out and saw Gaster she stoped.

"G-Gaster?"

"Alphys what wrong with you help me attack this idiot!" Undyne told Alphys.

"N-no it's the old royal scientist, Gaster"

"Ma he called me subject....and he said a lot of numbers." The child said.

"Uh G-Gaster this I-s m-our child Ev-"Alphys started

"He has a name you weird old guy." Undyne tried to defend.

"My name is Everett!"

"Well..Everett is Asgore here?"

"Uh w-we'll h-he died and now To-Toriel is ruler of the underground it-s su-surprising that s-she is still alive." Alphys cut in.

"Well can I go see her?" Gaster asked.

"Yeah sure just don't do anything bad or Everett will attack."

"Oh I'm soooooo scared" Gaster started walking inside the castle.

"AHHHHHHH" Both Undyne and Everett attacked.

"Oh my Asgore! Get off!"

Gaster stood up letting them fall off and walked torwards Toriels kitchen. He somehow knew she'd be in there.

"Oh hello chi-Gaster?"

"Hello Queen Toriel! I uhh have a question to ask do you mind?" Gaster really didn't want to intrude on her

"Oh please I'll answer any questions I mean you haven't been here for like a million years."

"Has it been that long? Wow. Well Queen Toriel do you know where Sans and Papyrus are.?

"Gaster, I'm afraid they are not around anymore, sorry." she seemed like she did something to them.

"Oh well thanks anyway Queen Toriel."

"Please just call me Toriel."

"Okay well bye Toriel." And Gaster walked out of the castle ignoring every one in the castle and in his way if someone got in his way he'd use his magic to make them move.
