The Sworn Protector

Let's Go.

I know it's going to be a shorty, but since I'm only going to be working mostly on Losttale, I can only come up with so much ideas. Enjoy this chappie before I go on break with the other books. I'm super sorry about this mega writers block I'm having right now. Thanks for your support!!

Sans went back home to Undertale. He wanted to check on Papyrus and let him know he was going to be gone for a couple of days. He opened the door to his home and looked around, knowing this'll be the last time he'll see it for a while. Papyrus was in the kitchen cooking pasta as always. He turned and saw his brother. "Sans! You're home! And just in time for my extra special spaghetti I cooked just for you." Papyrus greeted his brother. The shorter skeleton smiled. "Thanks Pap. Hey uh....after you're done, can I talk to you?" He asked. "Of course Sans. Just give me a moment." Papyrus turned back to his pasta and continued stirring the noodles. Sans walked back to the couch. He felt tired and decided to take a nap while he could.
"Sans.....
Sans wake up!
You need to go!
Error's attacking Underswap and we need you here!
Meet me where we first met
And hurry!!"
He opened his eyes and quickly sat up. "H...huh...?" Papyrus then came out of the kitchen and sat down next to Sans on the couch. "So...what did you need to talk to me about?" His brother asked. "It's...a long story. I won't be around for a while Pap. I'll be...gone somewhere and I don't think you can come. It's for your and my sake. Adding to that, the underground's sake." Sans said. He noticed that Papyrus' face was filled with a mixture of confusion and worry. "Don't worry, bro. I'll be back before you know it. You won't even know I was gone."  He added. Papyrus just stared for a second, probably thinking his brother has gone crazy, but since he was the loving brother he was, he gave Sans a reassuring smile. "Alright Sans. Just be careful out there." The tall skeleton walked up to his brother and wrapped his arms around him. By now, Sans' eyesockets were filled with tears. He hugged his brother back. "I promise, Papyrus." They just stood there for a moment, then they eventually had to let go. "I love you bro." "I love you too Sans." The short skeleton then grabbed his hoodie and ran down to the depths of Snowdin forest, finally on his mission at last. 

I wonder where the bold words came from...
