Swap
Why Swap/Blue Works So Well with Ink, Error, Nightmare, and Dream (My Interpretation/Thoughts)
🕸🎨
I think he works so well with those characters because he represents something most Sanses need in their lives but they lack: Papyrus.
Error and Ink lost their Papyrus, which is why Swap would fit so well with them—someone they feel at peace with. But they have little to no actual memories of their brothers. Ink’s Papyrus was never fully "baked," so he has feelings about that, but never had the chance to form a real relationship with him. Error, on the other hand, must have lost most of his memories through glitching. He just has the lingering sense that he must have had one, once upon a time.
Because they don’t have clear memories of their own Papyrus, seeing Blue/Swap wouldn’t hurt them (like it would hurt Dust to see a slightly different version of his dead brother)but calm them and amuse them. There are no painful memories to haunt them just the feeling that this one is good for them. (the reson i think Error lets him stay.)
Its why ink choosen him for the Starsanses its why Error kidnaped him
(Like, think about it almost every Sans, or character in the position of Sans, has strong feelings toward their Papyrus or sibling. It must be strange to lack the thing that mostly connects AUs and ATs.)
🌙 Now, about Nightmare and Dream ☀️
As far as I’m aware, they never had a Papyrus, but they were placed into Underswap Sans bodies (again, as far as I know). So they look a lot like Blue/Swap. This means Swap/Blue would look to Dream like Nightmare, and to Nightmare like Dream.
I think Dream would find a sense of comfort and acceptance when Blue is around—reminding him of the brother he lost, and maybe growing to be a friend, parent figure, or lover (pick whatever you like, lol). The same might apply to Nightmare + Nostalgie, at least the part of him that still feels and remembers.
This way, Swap can act as a sort of balance between the four someone who can talk to them, help form alliances, and sometimes just be a listening ear. This Swap is far gone from an classic Swap!sans he could have become an outcode at somepoint
Just something I thought about today :)
