The four main Robins having very different origin stories, antagonizing each other (almost to literal death) at one point or another, then eventually uniting because of their deep sense of love for and loyalty to Bruce, their mission to save as many innocent lives as they can, and, of course, to each other (whether they admit it or not).
They have so little and so much in common that it makes for such an interesting dynamic every time they share panels. (Regardless of how “horrible” the writing seems.)
I, um, think about this a lot.
