Having reviewed Arma's tenets I am reminded of the following
quote:
A Priest of Arma who displays cowardice in the face of evil risks being excommunicated
I would deem running away to be cowardice in the face of evil. Particularly when combined with this (Msg 30).
Raellus:
"A few of the sell-swords have come in here and paid their respects, but most of them have no devotion to the Warrior. They fight for personal gain and little else. As you well know, Arma frowns on bloodshed for profit. In fact, I wouldn't be surprised if many of them worshipped the Reaver."
Therefore Jenna is obliged to fight rather than run away. Chance to strike down some Reaver worshipers? Win win.
Clearly, no one else is obliged to fight with her if they don't wish to.
Alternatively, if you want to have Nic and / or Corros talk their way out of it that would also work.
