Jade and Equius having a robo-competition

Equius making snide comments about Jade’s mechanics.

Jade poking fun at how often he destroys his prototypes.

Equius sabotaging her attempts with a ‘misplaced’ hand, warping the parts.

Jade changing the sizes of his so that they don’t fit together.

Frenetic bickering over cheating; Equius saying that she’s just a lowly peasant that doesn’t stand a chance in he first place and Jade calling him a jealous asshole who’s scared she’ll beat him.
