Edith wasn't particularly competitive. But... Kara was pissing her off.

All you did was win a few fights, suddenly she believed she was better than you?

"Alright Kara. Come at me then."

She batted her broadsword against her shield. An invitation.

Kara smirked in turn.

"I'll mince you, hell, with a wooden blade even."

She smirked, brandishing the training weapon.
