I'm willing to kill anything for my kids.

Kids meet Uncle Blue.

Error got up, got ready, and walked to his living room to see his children all up, and to see Fresh serving them food. Error also took note of a phone that was hooked up to the wall. "Hey guys!" Error said, sitting down at the table with his kids. "Hi dad!" They all greeted. "Hey Error bruh! I showed them the ropes on how to use da phone! I also got then some rockin' good eggs n bacon!" Fresh said, putting a plate in front of Error, before washing, drying, and putting away the dishes he used to make the breakfast. "Well I gotta split! See ya later Dawgs!" Fresh said, going through the front door before poofing away.

They all talked a bit before putting their dishes in the sink, Error telling them that they were going to meet some people. PJ and Ember were pretty excited, Ember hoping to meet someone they could touch, while Gradient was excited, but wary, and Jupiter just full on nervous. When they were all ready Error opened a portal to Underswap, hoping to see Blue there.

When Error opened the portal to the au, he walked out, checking around before letting them come in. Ember on Error's left, holding his hand, and the others staying close. Error was sure to make it very clear to stay close and not wander off, as new monsters was weird enough (especially skeletons), but if he was seen by Carrot (underswap papyrus) it would be a whole new problem.

Error led them through the au, them admiring the new world as they had only been able to go to outertale, or look through Error's glitched 'screens' (aka portal, but he uses it to watch aus like a TV show). Eventually Error found Blue near the ruins door, telling his brother off about being lazy, before walking away. Error saw his chance, and grabbed his kids, teleporting where Blue was going, making sure no one saw him at the path between snowdin, and where Carrot was. Error then threw some snow in Blue's direction, landing near his feet. Blue was startled at first until he looked in the direction the snow came from and smiled. Blue walked up to Error, who was hiding behind trees, bushes, and snow, before speaking in a hushed tone. "Hi Error!" Blue whispered, "Are these the kids everyone saw?" He asked, taking note of the children hiding behind him. "Yeah, where can we meet?" Error asked, looking back and forth, scared Carrot was going to get suspicious. "Teleport to my house, I'll be there in a bit." Blue said, waving goodbye before waking off.

Error got up, teleporting everyone to Blue's house. "Who was that dad?" Jupiter asked, wary. "He seems to really like Blue." PJ said, trying to making fun of them. "Correct." Error said, making then look at him confused. "His name is Blue." Error clarified, sitting on the couch. "Oh! Is he the one you mentioned that one time? You said he saved you or something..." Gradient said, trying to remember. Error nodded, and stated they just needed to wait for him to get back. They all ended up sitting on the couch, practicly laying on Error, this time Gradient was in his lap, PJ to his right, and Jupiter to his left, holding Ember.

It took a little while for Blue to show up, and when he did, he smiled brightly at what he saw. They weren't asleep, but they all were definitely very comfortable. Error looked at Blue, before nonchalantly saying "Hi Blue. First off, meet my kids." Blue stared at him for a second with a smile, before his eyes turned to stars and he yelled, "Whaaaaat!?!?"

When Blue finally calmed down, he was very excited. "What are their names? Does this make me an Uncle? How old are they? Who did you get with? Why did you keep this from me? How could you keep this from me?!?!" In the end Error had to calm Blue down again, while the kids watched from their seats on the couch. "Wow, Uncle Blue is really..." Gradient started, not sure how to phrase it. "Weird as fuck?" PJ said, "Very passionate?" Jupiter said, having already taking a liking to him, especially liking how his eyes turned to stars. "How about cool!" Ember said, still sitting on Jupiter's lap. In the end Error explained how they came into reality, telling him that Ink was a parent still alive, and telling him how he met each of them, even explaining why he kept it a secret. Blue nodded his head, taking it all in. "So what are you going to do now?" Blue said, looking at this kids on his couch. "I'm planning on visiting the gang, I was hoping I could leave them here with you." He said, "They might want to destroy, so can you tell Ink and Dream you won't be able to come today?" Blue looked up from them, smiling at Error. "Yeah, sure! We were going to meet up today anyways, so telling them I won't be able to make it won't seem weird and random. Besides, this means I'll be able to hang out with my brother's children." Blue said, winking, and with a huge smile on his face. Error said goodbye to his kids, before leaving and going to Nightmare's castle.

Hope you enjoyed! See ya!
