Equal means that they don't need each other because they're both fantastic. I've seen this. Basically separate lives and then they sleep sexlessly in the same bed. Or equal means that they're both complete fuck ups helping the other drown faster in whatever combined shitstorm the two of them are generating.
Absolute equality seems like an unlikely find.
Forcing equality on an inferior is asking for trouble.
Dragging someone down a couple level seems unfair too.
Lets go cornhole a unicorn while we're at it.
