Difference between C-u edge and plain edge?

I haven't used the edge annotations much (and I'm not using org-brain that much these days, unfortunately). But if you're visualizing A and have the point at B, pressing e would make a two-way annotation like A <--> B, while C-u e would make a one-way annotation A --> B. If you're later visualizing B you would see the two-way annotation, but not if it was a one way annotation.

If you're at A I don´t think there's a command to annotate A <-- B. You'd have to visualize B, put the point over A and use C-u e.

Okay, I did your last suggestion (viz B and point A then C-u e) and yes, it created in B file #+BRAIN_EDGE_A: is-in ... which can be interpreted as B is-in A. But then viz A and point B doesn't distinguish between e and C-u e, both produce the condition I mentioned originally. This is acceptable because one-way or both ways A ->/<-> B as long as there is A <- B is workable.

As I might have said before, I really appreciate org-brain because it offers org-mode the way it should have been done, i.e., graph and not just hierarchical outline. You've given org-mode a brain! The others are nice, however, e.g., org-roam, isn't really brainy enough.
