Even when he wasn't in his right mind he sensed Barbara coming. Like Bruce he was trained to see without sight. Use his other senses. He didn't even flinch when she approached, only the sound of her voice made him cringe-because in his ears, it sounded like nails on a chalk board. His ears were sensitive to sound, any kind. Voices or inanimate noises. He took a slightly shaky breath and pulled one knee to his chest. At least he'd found some spare clothes in the tower that probably belonged to Bruce. Black shirt and jeans, but anything was better than hospital scrubs.
He was quiet even as she came up. Everything was overwhelming. Terry didn't know how to deal with having a new father, and being kidnapped. It was all new territory. His chin was resting on his knee, and his other leg dangled over the ledge. Being inside that Clock tower was starting to feel more like prison than the Joker's trap. He didn't say anything but there was a restless look to his eyes that was probably pretty obvious with his exhaustion and inability to bottle emotion. But he said nothing because he didn't want to offend Barbara, he knew she had good intentions. Terry just felt like he was caged, and it was getting to him. So he needed a break.
"Wasn't that hard.." He finally said. His voice barely above a whisper. At least this night it wasn't raining. Terry didn't find the blind spot by accident, he'd mapped things out the best he could mentally and snuck out when the opportunity was right. He was Batman in his time after all. "I'm not stupid." He retorted somewhat shortly. "Technically I haven't left the tower."
