. The poem talks about how Robin has grown up after separating from Batman. It seems to be a poem about growing up, the complexity of relationships between siblings and parents, a student becoming the master and a gradual disillusionment with one's childhood heroes.

The poem portrays the bitter tone of Robin as he leaves Batman and reveals the truth about him.
