Incest isn't my thing, even if they weren't really brothers, they'd be KILLING each other from their auras

Their personalities don't mix well either, they're completely opposites.

Sure, I love ErrorInk to death and those two are opposites, but they went through similar experiences and have the same reason for what they do, but different interpretations of it

With Dream and Nightmare, they have the same past, and are the reason for each other's downfall.

Look at it this way; if they were together, would they help the other be a better person? No, not really

Nightmare's most likely not even capable of love

So yeah... the ship's a no for me
