maybe it was because he was used to it, you know? the night streets, fighting crime and anyone who was willing to take away his peace, being batman's right-hand man is his thing, maybe that was all he knew; and when a chubby-cheeked one-year-old little thing appeared to take him from this life, he hesitated.
