a bunch of scenerio sketches of the two

top row is an idea for them adopting a pet, literally ripped kill-a-pillar from Amphibia, unsure if she would be full kill-a-moth though. Her name is Nybble

bottom (from left to right)

1) part of a deal they had after ohm helped her out with techadons, resulting in part of her ship getting wrecked. Spark regularly ends up with way too much mana build up, and so she lets Ohm drain her excess energy and convert it to on ship batteries

2) saucy

3) last one is their first meeting when Ohm catches Spark on her ship, it was not love at first sight
