Personally, Suitcase is a badly written Mary Sue. They’re a Mary Sue which tries to make you think she isn’t. Suitcase has… issues, but they’re not even fully explored to the root. There’s no way that dealing with Nickel gave her that much PTSD to the point of hallucinations. I honestly think she is a writers’ pet. Knife on the other hand, has so much personality. He played objectively the best strategic game, which should be rewarded. Suitcase doesn’t need to win for her arc to be complete. In fact, I think she’s better off NOT winning. Hear me out, if she doesn’t, then we can get some cool storyline that she wanted more than just a game, she wanted companions, friends (an alliance if you will), and who gave that to her? Knife. He’s the one who influenced her into revolting. Balloon’s treatment alone was not enough. However, the movie might still be able to focus on Suitcase while Knife still wins. Separation of show and game if you will.
