#super-hearing

Okay, so something I think I should probably clarify is that Danny’s “super hearing” is very, let’s say, conditional in YJ:DW.  It’s not so much a permanently active thing that he’s aware of and can consciously tap into like Conner can,  and more of a stress response/ hypervigilance deal.

When Batman and Robin first find him, Danny’s been on the run for roughly 9 months and is carrying around a lot of unresolved traumas due to the losses he’s suffered and being hunted by a highly skilled, seemingly ever-present organisation who’re trying - and on one occasion very nearly succeeded - in capturing and experimenting on him for study, none of which he’s been able to stop and process.  At this point his senses are basically a bunch of raw nerve endings and his reactions are on a hair-trigger.

Once he gets to the Batcave and is able to properly internalise the idea that he’s actually safe things start to drop back down to a more normal level (although as a halfa his baseline will always be a little above the average human).   He could probably sense heartbeats at up to 10 yards in a quiet space if he focused, but there’s a difference between hearing potential threats in a dead silent storage locker when you’re jacked up on adrenaline, and being able to calmly listen in on a whispered conversation across a room the way Superboy can.
