Grillby x abused reader ( love at first light)

why should I trust you

Recap

(As yn was running she didn't notice that her flower crown was getting covered in blood as flowers fell from it and her clothes . Leaving a eerie blood trail behind her. As the fish lady is hot on her heals .
At this point yns getting light headed but keep running as she does she notices that is getting warmer as they run out of water fall into a new land scape as they pass a closed hotdog stand .)

~~~Yns pov~~~

Its really getting hot it's hard to breathe I'm so tired .but I can't stop I hope Grillby can make it in time to help . I can't feel my arm that much and my side hurts . Up ahead I see a stretch of ground above a pool of LAVA WTF ! I have to be really careful or I'm a goner . I'm about half way over the land bridge. "Your finished !" My vision flashes white with pain as a glowing spear forces it's way threw my torso . I fall to my knees and turn to the fish . As I do I notice she is about to fall of the edge . I can't believe I'm doing this ! " Noooooo" as the fish lady falls I grab her arm using all my remaining strength to hold on.

~~~No ones pov ~~~~
As Undyne miss steps and plunges towards the lava a blood covered hand wraps around her own following a shout "Noooooo" Undyne looks at the (y/h.) Your hair color) headed human "I'm trying to take your soul !why are you saving me? You stupid human! The girl sheds a tear "because no one deserves to be hurt and I can't let you die , let me pull you up hold on" yn pulls the fish lady to the edge of the ground. Undyne pulls herself up the rest of the way as yn collapses . "Oh no this isn't right I can't let you die if you saved me Dammit ! " yn looks her in the eye and hands her the last bloody echo flower in her possession the one she saved for the front of the crown the one that whispers "I love you handsome" and smiles sadly "give this to my soul mate Grillby for me ok?" Undyne hangs her head debating on what she should do as what the human said sinks in Soulmate ... Grillby that is all she needs to make her choice . Undyne lowers yns hand back to her chest with her flower still in it
"Give it to him after I save you I can't let you die now not after you saved me I'll take you to Alphys she will heal you!" Undyne picks yn up bridal style before running towards Al's lab .

~~~Undyne's pov~~~

The human feels so cold I got to hurry or I won't make it to Al's. She saved me while she was dying .when I'm the one that tried to kill her .she reminds me of frisk kinda looks like the punk too. Not to far now . A quiet voice breaks my train of thought." So what's your name Miss." I can't understand this human being so kind to me ." Undyne, what's yours squirt ?" She chuckles . " It's Yn ." I smile it suits them. " I think I'll call you mouse because your short and quiet " she smiles I can see the lab now almost there . As I push threw the doors I see a flash of blue this is gonna be a problem .

~~~when the fight was happening ~~~

Grillby continued to follow the trail of blood to Sans's hot dog stand when a flash of blue grabs his attention. Sans teleported right next to a frantic Grillby looks at the ground and back to the manic fire man "Undyne caught yn . Sans runs after Grillby with his soul pounding against his ribs. before teleporting to Alphys lab to head them off.
~~~~back to the present~~~~
Sans pov

I can't believe what I'm seeing IN front of me ! Yn the harmless kid the woman that never once try to hurt any of the monsters they come across . Bloody with a spear In her stomach and cuts to her arm and side in the blue bitches arms . She looks dead . My eye flashes blue and yellow ." UNDYNE give me the kid now or your gonna have a bad time !!" To my surprise she gave her to me without a single argument I check YN for a pulse and find one I yell for Al and she comes rushing in with a first aid kit with metta bitch trailing behind with a bed she must have seen it on cams . I set yn on the bed and Alphys kicks us all out of the room and shuts the door to work on the kid .
"What the fuck Dyne yn is a pacifist and she is frisk cousin what did you do!"

She sweat drops and looks down "I was bringing her to Al I realized she was an ok human because I tripped and she helped me I don't want to take her soul anymore!"
Just as I was about to say something a fire ball flew past Undyne's head . "What make you think you can attack my soulmate and get away with it where is she?!" Grillby melted the doors to the lab he lost it . I smirk a bit as Undyne lowered her head . "I brought her to Alphys to get healed realized my mistake and I'm making it right !"

Grillby continued to raise in temperature "why should I trust you!" Right as he said that Al comes out of the room with blood on her lab coat " s-sh-she i-is s-st-stable for now s-sh-she will need help for a bit until she's fully healed . You may see her now !" Me and Grillbs walk to the door . Undyne walks up to but Grillby cuts her off " NOT you"
