You try to distract them

Nell and Adi are both much larger and stronger than you and there's no way you could physically stop them if the situation came to blows. Jon notices the potential for escalation as well and stands up, though he looks visibly nervous at the prospect of trying to break up a fight.

As your mind races to come up with a better outcome, you realize you do have one trump card left up your (metaphorical) sleeve. Quickly you shrug the blanket off your shoulders and let it fall to the dirt. With a deep breath you feel your magic coalesce in your core. Focusing on your quarrelling party mates, you holler over to get their attention.

"Hey fellas, there's no need to fight. I can help you relieve some stress," you holler at them as you squeeze your breasts in both hands. The magic from your Charm spell fills the entire campsite instantly and both Nell and Adi stop their posturing to stare at you. For several long seconds everything is quiet as your magic dissipates throughout the environment.
