Okay so in the 1st one they are wearing fun Halloween costumes together and the bonus second one is because aradia is dirty from digging for bones

I think they're cute! Aradia and kanaya both have a thing for the dead (aradias archeology hobby and actual death along with kanayas zombie hunting/vampire literature) so maybe they have dates where kanaya beats up zombies and aradia tried to guess how they died or smth!

And also since aradia likes archeology maybe she shows up all dirty and stuff and kanaya is like "No" and sprays her with a hose kinda like this

Alternian rain has the acidic properties corrosive enough to melt a young troll’s eyes out of their skull if outside during its fall. Luckily for trollkind, rainfall almost always occurs during the day, when a young troll is fast asleep.

Unluckily for Kanaya Maryam, a young troll who spends all her wakefulness in the scorching sun and toxic clouds, rain prevented her from enjoying her day. Instead of strolling outside or reading a book under the awning, she was forced to avoid certain death, cooped up in her spacious home.

It was on these days that Kanaya would hear the familiar notification sound from Trollian, and rush over to answer her friend, Aradia.

AA: hey kanaya, y0u b0red yet?
