Spoil, what spoilers? What is there to even spoil?
Krennic dies, most of the rebels die, the Death Star plans are sent to Leia, a planet is going to get destroyed, etc. The female Kyle Katarn, British chick doesn't even matter. She's fluff, she's fairy dust, she doesn't exist, she isn't real. She's a stock character that you're introduced to as a child to try and force the audience into being emotionally invested. We've seen it a million times, hell, we just saw it with Rey last year (little girl separated from her parents as she sees them leave from a distance). After next week it doesn't matter if she lives or dies, the end result is still the same.
