Training sessions at the Batcave be like…

Batman: *powers off the villain generator*

Batman: *watches as his sons get up from the various places they ended up in, dust off their bloody and singed suits, and groan in pain*

Batman: …

Batman: Well, this simulated disaster is a total disaster.

Alfred: *goes upstairs to grab some tea and medical supplies*   

And it’s this familiarity with homemade disasters that makes the Robins experts on the field.
