Man, this was hard to watch. This is where we find out that the deal that V mentioned in Cabin Fever wasn't just a blanket deal with the trio, but a specific bargain V made with Cyn to protect N. She's been masking all this time, keeping N at arm's length and being the best murderous psycho she could to keep Cyn away from N. And then the mask falls, and she's just a terrified kid believing she's just lost the one person who mattered most to her.
Imagine what it must have felt like to see Uzi use the Solver for the first time, and to watch N and Uzi grow closer. She didn't even see Uzi; she saw Cyn, taunting her with the threat of taking N from her and daring her to try and do something about it.
In that context, V's decision to place her trust in Uzi was the MOTHER of all character growth.
