Why are they "brothers" though, and what purpose does Tim being a fan of Dick's serve. Remember Tim was coming off of Jason as Robin. Being brothers, Tim being a fan of Dick, none of this is character driven or there to serve Dick. None of that has really done anything for Dick's overall character. We saw more character growth for Dick with Damian then the entirety of Tim existence has done. Those bonds are purposely deigned for the underline purpose of getting Tim over, so that fans didn't reject him like they did Jason. Its all about Dick giving him the A-ok. That is the basis in which those bonds were built.
