Nightwing is the one person Robin Damian Wayne is closest to, so it stands to reason that Damian’s best friend, Superboy Jonathan Samuel Kent would warm up to Dick Grayson easily.
This is the first meeting between Dick and Jonathan, given that before the Rebirth or New 52 reboot, Superboy was Conner Kent. Dick tries to put Jon at ease by juggling rocks after the latter flew at night and got lost, prompting a massive search by Superman and the rest of the Justice League.
