Why must he feel like this. That was a villain, someone he shouldn't even feel tolerance for, but now he lies in bed, thinking about them. He didn't even get to see their face, it was simply their agility and wit that amazed him.
He groans and rolls over, smashing his face into his pillow. He's so tense, he could break like a glass table. He feels as if he's on the verge of insanity.
When he can't take it anymore, he shoots up out of bed and leaves his room, sneaking down into the batcave. He gets his costume and puts it on.
With a huff, he walks over to the table and grabs a pen, writing down on a piece of paper 'sorry, Bats, out on patrol -Drake' and then leaves into the city.
He will find this villain. Not to capture them after they got away. To figure out what their deal is and why he feels this connection.
