To keep track of Damian, Bruce embedded 4 tiny tracking chips into his Robin uniform. Of course, Damian promptly found and removed them all within a month. He then preceded to surgically plant them within Alfred T. Cat, Titus, Batcow, and Jerry T. Turkey. But what Damian doesn’t know is that Bruce actually planted a 5th chip underneath Damians skin, during the first time that Alfred had to sew a knife wound closed. Like Father, Like Son.
Batman can be savage. He sees The Riddler stuck in virtual reality and without even trying to get him out Batman’s like “Huh, guess this is unsolvable. He’s probably trapped in there forever.” and then he just leaves. It was harsh.
