The 7th Cavalry embraced some distorted version of who Rorschach was and mixed some of his philosophies in with their alt-right ideals, but when it comes to the true embodiment of what Rorshach believed, we see those ideals in Sister Knight. When Angela Abar discussed with her kid the ways of the world, Rorshach's voice shone through in her lesson:

There are people who believe this world is fair and good. That it's all lollipops and rainbows. We don't do lollipops and rainbows, because we know those are just pretty colors that hide what the world really is... black and white.

Personally, I think the above quote alludes to more than what it's saying. I know many people who only see the world in black and white, and by doing so, they miss out on the subtle shades of gray. The show tackles many social issues of today, and when looking at real people, nothing is ever just black and white. I think we see this in the relationship that Angela Abar had with Judd Crawford. When she pulled out his 7th Cavalry robe, I automatically said, "I knew it. I knew he was part of the 7th Cavalry." But let's be honest, this probably isn't the case at all, and as Sister Knight continues her investigation, I think we'll see there's more to the robe than meets the eye.
