User blog comment:ChishioKunrin/How the plot has used Ruby Rose/@comment-3387274-20170721120819

There is only one bit of Ruby's character I haven't seen mentioned here, and that's her attitude to fighting people. In Volume one and two, she always uses a reversed grip when fighting human opponents, hitting them with the blunt side of crescent rose rather than the blade. She still shoots at them though. When she fights Neo in V3, she is using the Sharp edge to strike instead, and she continues to use the cutting edge up until Tyrian loses his tail. Since we haven't seen her fight a person since, it remains to be seen how the trend will continue.

The thing is, shooting people a d throwing them off trains isn't sparing them, and some of the white gang she fought in V2 died in the tunnels. She's just making a deliberate effort to be merciful instead of thinking about what she's actually trying to do.

Seems to me that Penny dying might have made her realize that she's dealing in matters of life and death, and she responded by dropping her token gesture of non-lethal fighting.

Or it could be that RT's animators didn't notice a subtle gesture on Monty's part. Hard to tell at this stage.
