Claire's attitude is infuriating, but there's not actually anything wrong in what she's staying. Steph keeps her eyes on the enemy to avoid glaring at her friend and resist the urge to slap her. She can't help rolling her eyes though.

"Forgive me for trying to avoid getting shot," she mutters sarcastically, fingering the staff at her back.

"Do whatever you want. But learn how to use that thing or leave it behind," she retorts at normal volume, turning to point at Claire's sword. The moment the words are out of her mouth she regrets them. She sounds like Batman even to herself, and that's not something anyone should aspire to. She quickly turns away, clenching her teeth, turning a little bit of that bubbling rage on herself. She spots a usable ledge in the proper direction and jumps for it before either of them can do something else they'll regret.
