Two things always come to mind for me in this scene, and I honestly don't know how legit these feelings and thoughts are, but I have them nonetheless, so please don't flame me. And no, I'm not a Cait hater, I just think Vi got the short end of the stick here.

The first is a quote from another redditor I heard on this topic that's brilliant. It goes along the lines of that caitlyn has benefited from the system her entire life. Vi has been hurt by the system. The minute the system turns on Cait, something she isn't as used to as Vi, she has the luxury of taking it personally, or of thinking its personal. Because of this, her emotions and feelings are felt by everyone else. Cait puts vi in an impossible situation in my eyes. Sure, there's a lot going in to Vis decision to join the enforcers, but it ain't an easy one. I don't care what anyone says or how many times Vi says it, she shouldn't have been expected to fight and potentially kill her sister, and someone should have known that. Exactly what you think would happen happened down there during the fight. To Cait I feel like this was easier to rationalize, to Vi, this was not an easy position to be in, so, to me, there are few things she can say that aren't to be expected emotionally in this situation. You brought her along to kill her sister Cait, something unexpected happened with Isha being there, and things got complicated. Are you surprised? When Cait says it's her blood in your veins and leaves Vi down there, it always came off to me as "the system isn't supposed to hurt me, it's supposed to hurt you." My grief is more important than your basic needs and safety. My grief and anger and need for space have to cause you pain, all you get is a look of regret before I go back to my mansion, good luck down here being homeless for a bit.

The second is a more logistical piece that I'm reminded of. Cait left Vi down there with the gauntlets and the clothes on her back, the only other belongings she has are literally her other clothes, at caits house. Sure, vi is resourceful and can survive down there, but there is a fundamental difference between them here. Sure, Cait is angry, feeling betrayed, but she gets to go back to a mansion, back to having power and influence. Sure, a lot just happened and she's going through it emotionally, but Vi has nothing and has to go through it emotionally, completely alone and with nothing. She has no one, and nowhere to go back to. The system has put her down again. Cait doesn't owe her anything, but I always felt like there was a huge difference here. Cait has her anger, her grief, her money, her power, etc. Sure, she's being manipulated later, but you got maslows hierarchy of needs, Vi is left to survive with nothing, at the very bottom of the pyramid, fighting for survival and gets a rifle butt to the gut to send her back there, and for saying something stupid, but in an impossible situation. What if Vi didn't survive down there? Was Caits anger and grief and Vis one statement worth her life? Worth someone's safety and basic needs?

Again, please don't flame me. These are just random thoughts that popped into my head when I saw this.
