The brother of Sans and Pap.

Meeting Ben!

So about sixteen years ago, after W.D Gaster's disappearance, Grillby woke up to a baby's cry. When he finally got out of bed and to the front door of his restaurant, he saw a bundle of blue and orange blankets. The blankets let out a small cry, Grillby was a little afraid of picking the blankets up, but he did. He brought the thing inside and looked under the blanket, he found two things a baby fire skeleton and a note. When he read the note, he almost cried, he looked at the child and made a solemn​ vow. That vow was to raise his and his "friend"s baby.  (BTW the note said "To my dearest Grillby, this child is a peace of both of us, I created him in my lab. If you are reading this I am dead and my apprentice has given you our child, he was created for you, and for since, just like his brothers. Please keep him, he will be the last thing I have created, he was created out of love and fear. From the newly departed friend of yours W.D.G.)

~~~~~~Five years have pasted~~~~~~

Grillby was busy doing his job as being a bartender and a restaurant owner,  Ben had snuck down stairs into the restaurant. Luckily for the little guy, a teenage skeleton with a blue jacket and shoes picked him up before anyone could step on him. "We'll look what the cat draged in" he said with a chuckle. Ben saw another skeleton, but this one was smaller and wore red and orange, he was face palming. "Sans, please no more puns, yes that was a good one, this child does have cat pajamas on, but no more please. I'm Hungary." The little one said. "Alright Papy, but we need to find out who this kid belongs too." Sans said lazily. The brothers walked to the bar with the little "kitten",  Grillby only had to take a glimpse at the brothers to know that is son was out of bed.

Grillby was upset that his son wasn't in his room like he was supposed to, but he was happy that his brothers found him. "Hey ya Grillby, can you get some Chow for me and by bro here? And do ya know who this kit belongs too?" Sans asked. Grillby cooked the boys a meal, spaghetti for Pap and a burger with fries for Sans. He also gave Ben a glass of warm milk and said " Well Sans I'm a little hurt that you can't see the resemblance that little one and I have, but his other parent was a skeleton after all." Sans and Pap's jaws almost hit the counter, Ben was giggling and drinking his milk. "S-so this is your kid!?" Both brothers asked and said in unison. Grillby nodded and then asked to Ben " Grill, would you like some more milk?" The little one nodded.

~~~~~~Many years later till he turned sixteen~~~~~~

"SANS! Where are you lazy bones!" Pap said with annoyance in his voice. Ben was bringing some groceries home when he heard Pap basically yell that. "Hello Pap!" Ben yelled in return. Pap was a little shocked to see the teen, but was also happy to see him. "Hello Benny, have you seen my brother?" The skeleton asked. After wincing at the nickname, Ben said " Sorry Pap, I haven't seen him today, but I could use some help, he may be at my place." Pap nodded and grabbed some of the groceries from the smaller one.

When both of them made it to Grillby's, they both found Sans, Mettaton, Undine, Alphys, the King and Queen, with the human called Frisk there. "Hey bro!" Sans yelled when they entered, Pap gave him an look that might actually be able to kill. "Surprise Daring!!" Mettaton chied, Pap's face looked a bit happy, but you could tell that he was still a bit mad. "Hey kid!" Ben heard Undine yell towards him. "H-hello B-ben." Alphys said quietly, Ben only waved a hand since his arms were full. He took the rest of the groceries from Pap, the then put them in the kitchen, where they belong. When he finished he went out and sat with his friends. "Hello everyone, especially the royal family?" Been said with bow. "Day by day you look more like someone we both knew."the King stated. "Like who? My dad?" Ben chucked. "B-ben m-more l-like the r-royal s-so before m-myself." Alphys stuttered. "Really what was his name?" Ben asked with a playful tone. "W.D Gaster, mine and Pap's dad." Sans said holding a katchup bottle. "W-well my last name is Gaster, are you guys punking me?" Ben asked while looking at his father. "Not at all!" The King stated. "Ben why don't you find the man who speaks in hands." Frisk said after finishing their pie. Ben got up and said "well I need to help my dad, this place is packing up...... Thanks Mettaton." He then went to the kitchen and froze, how did the human know of his old imaginary friend?
