well... she also does not know that rae risked her life and sacrificed 7 of her best and closest warriors(not including the pilots) to buy her time, soooo there's that ^^
if she sees Rae, her assumption will be that she somehow blundered into the fort and got herself caught in some stupid way!
Fair enough!
When she sees the catastrophic damage done to the fortress, things might make a little more sense. ^_^
