This is a AU where Sans and Frisk are married and have a daughter named Nadia. Frisk went through he Underground but unfortunately wasn't able to break the barrier leaving monsters still stuck Underground. Sans also known as G!Sans because after an accident in the labs Sans and Gaster fused together letting them both live. Sans unfortunately lost his ability to glow blue when he fused with Gaster making him glow yellow in both eyes but prominently in his left eye... Since he is fused with W.D. Gaster... Nadia wears a grey sweater with a heavy dark grey jacket over it with a gaster blaster patch on both sides like sans, she has a red skirt with blue jeans on like Frisk... she has a golden/Ruby red heart locket on with pictures inside of it, she keeps her sleeves up showing her right arm to be skeletal like Sans and her left arm is human like Frisk, she has black gloves over her hands but openings for her fingers... Her eyes are golden yellow but when Angered or threatened they can turn bright yellow... At waterfall Nadia is sitting beside lots of echo flowers with her notebook and pencil Nadia: ... so... if we need a human soul to brake the barrier... why don't they just... make one? Echo flowers: ... so... if we need a human soul to brake the barrier... why don't they just... make one? Sans: because it was too dangerous... and it... it's not happening again Nadia jumps and drops her notebook as Sans chuckles and takes a drag out of his Cigarette and stops it out as Frisk is leaning against him Nadia: DAD! D-Don't scare me like that! Her eyes flares yellow and Sans nods Frisk: hehe... I think he got you.... and he has a point She smiles as Nadia rolls her eyes as Sans rubs the holes in his palms and he summons his yellow Scythe and spins it around as he looks down at Nadia
