These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Alternative Character Interpretation: Ashley is the squad member who give you the least flak in combat, frequently uses herself as bait so you can snipe enemies (clumsily) from afar and helps with the most important or dangerous missions, and your revenge for Susan. Judging from what she is willing to do in these missions to fight crime and her trust in you, her defection to the Vipers in the end is more likely out of her genuine sense of duty than power hunger like Decker.
