kanaya's perspective differs mostly from experience. in the past three years she's been through each of them at various times, though her experience with pale is very different from karkat's and none of her auspisticisms have ever been successful. black and red though, she can tell you a lot about them.

but the thing about arrested restraint is she is by no means the person it's most telling for, just probably more obviously since she'll actually talk about them and acknowledge she's read them
