(Error's canonical haphephobia.)Every Sans knew that Ink and Error had a weird chimestry,but didn't comment as it was common to them.They have seen Error and Ink fighting and arguing,but it was merely random and minor reasons,like Ink stealing Error's chocolate bars to give them to Cross,or Errors stealing Ink's vials to hide them.One day,some of the Sanses wanted to see if Ink actually felt something for Error and they spied on them when Ink came into Error's Anti-Void to play.
