The Underground: Part 3

                                    

                                          
Alright, so I decided the official number for the parts of the underground. The next part will be the last one. Also, I know the last two parts have had a little drama here and there, but there's going to be something a bit more drama-ish this time around. Oh yeah, (f/s) means favorite song.

Your P.O.V.
                          
     It was now Saturday, which means tomorrow is the last day underground. Your goal was almost complete. On the second day you made Toriel and Mettaton happy, well except for when you and Frisk were listening to Mettaton's conversation with Sans and Papyrus. Throughout the week you had cooked with Undyne(and gladly didn't die), watched anime and comforted Alphys about the true lab, hung out with Napstablook while listening to his songs, solved puzzles with Papyrus, and watered flowers with Asgore. That was almost everyone, except for Sans and Frisk.
                          
     Sans...hm...you could probably take him to the old Grillby's or give him a bottle of ketchup. But, knowing as he's a partial man of mystery, it probably won't be that simple. Frisk however, is a different story. Maybe a trip through the underground with them? Although, maybe not to the room full of coffins...you could only read the first name since the coffins were to big to get around...Chara... That plan probably won't work though... They got sick, so you had to stay at the brothers' home the entire week, never making it to the ruins. It's going to be hard to interact when they are curled up in a blanket on the floor. 
                          
"(Y/N)," Toriel calls for you. "Frisk has something to ask you!"
                          
     You walk over to Frisk and kneel on the floor, waiting for their question.
                          
"C-Can you go to the ruins?" The whisper, voice a bit scratchy.
                          
"Wh-what? I don't know my way around!" You respond.
                          
"Then, how about Sans takes you?"
                          
"Does he know his way around the ruins?"
                          
"No, but he knows how to get there. And Toriel is taking care of me...and her past...well, she's protective so she probably won't go...with me being sick."
                          
"Well why do you want me to go?"
                          
"There's a tiny yellow flower down there who's different from the rest. Please, bring him back it'll make me happy. You'll know it's him, and he may seem like a bit of a jerk, but please, bring them back for me..."
                          
"Ok baby sibling, I promise."
                          
     You give Frisk a small pat on the back and go to find Sans, telling him of your task. Also explaining why Toriel probably won't take you. As you head out with him he tells you about Snowdin. Grillby's and the little shop that filled the town with freshly baked CinnaBunnies each morning. Supposedly, the smell was amazing. You go through an area of snow and hear about all the puzzles placed out. The two of you stop when you reach a stand filled with empty ketchup, mustard, and relish bottles. Along with a lamp conveniently shaped like your younger sibling.
                          
"you know, this is where frisk first saw papyrus. and that bridge over there," Sans points to a bridge. "that's where I first met them."
                          
"Really? H-how did Frisk do in this cold?" You say, rubbing your arms for warmth. Maybe wearing a T-Shirt wasn't the best option.
                          
"Well, first of they were wearing that sweater they always wear. Second, you look cold. Here, take this." He says, taking off his jacket and handing it to you.
                          
"B-but wh-what about you," you stutter from the cold. "W-won't you g-get cold?"
                          
"I'm a skeleton. I really don't need it to be honest."
