Goat-napped

A few months later and Y/n and Nightmare, the new nightmare, have slowly gotten along more, with Y/n being bored and going to Nightmare to play since there isn't anyone else around. Nightmare is both amused and unamused by this, since he is also bored and has nothing better to do since they are the only ones in the au they reside in now. Y/n still questions Nightmare about what happened to Dream, but he always avoids the question...however, Nightmare has figured out a way to transverse the multiverse by using negative emotions...Nightmare has debated teaching Y/n how to travel, but decides against it.

At the current moment, Y/n is in their room, drawing their imaginary friend and humming. Y/n draws on the paper, using greys, whites, blacks, and some blues. Y/n's tail flicks as they keep drawing, bored out of her mind.

Y/n, pouting: if only I had friends...maybe praying will help! : D

Y/n sits up and gets in a praying position, closing their eyes.

Y/n: dear stars, may you please send me a friend? Maybe an angel, the nicest angel you have...I don't want to be lonely...I have my brother, but he's being mean and annoying!

Y/n sighs and rolls over, going back to drawing and unaware of Nightmare listening, and then leaving. Y/n keeps drawing, pouting and not minding the sudden chill that happens, or the subtle clink of something metallic.

???: Heya kiddo, how've ya been?

Y/n, perking up: Reaper!

Y/n sits up and looks at him with a smile, and Reaper smiles back, sitting down next to Y/n.

Reaper: Heya kiddo, how have you and your brother been?

Y/n: We've been fine! Bored, but fine! It gets so boring doing the same thing every day!

Reaper, chuckling: yeah, I bet so. How are your powers comign along?

Y/n: fine, but Nightmare won't let me practice teleporting!

Reaper: oh?

Y/n: yeah! He says it's for my own safety, but I won't go far! I just wanna explore!

Reaper, chuckling: seems like you want a moment to adventure

Y/n, pouting: Reaper! That was horrible!

Reaper, laughing: aw come on! Tibia honest, I have a lot more up my sleeve

Y/n, pouting more: Reaper!

Reaper, laughing: alright, alright...say Y/n, want to visit a friend of mine? I think she'll like you.

Y/n, blinking: really? Who?

Reaper, chuckling: Life. she'll love ya

Y/n, eyes widening: I can meet Ms.Life?

Reaper, nodding: yeah, but only if you want to, kiddo

Y/n doesn't even think about it, before nodding rapidly, causing Reaper to chuckle. What can I say? Y/n is an excitible child and they trust Reaper, unknowing that he is trying to get Y/n away from Nightmare because Nightmare has slowly started to go off the deep end, and he doesn't want Y/n to get hurt by him...yeah...he's totally gonna adopt Y/n sometime soon.

Reaper: you ready to go? Anything you want to bring?

Y/n, shakes head: no

Reaper, vaguely concerned: you sure? You goat nothing to bring?

Y/n: no.

Reaper gets more concerned, before sighing.

Reaper: alright, grab onto my cloak and I'll teleport us there
