Can't Pass Up a Pen Question

There is a complete mind map of the episode of mine maps. I'm happy it does, cause it's nice that somebody will put the work in. But i just don't get what the mind map is doing. And then a question that i couldn't ignore from burn on twitter. So if you look at the original image of adina's work, there is some blue writing. She is using an ink called pilot eroshezku con pecky. They both come with thorough recommendations from me. Can't pass up a pen question. No, you're penaddict. That's what you are.
