Rock, the only truly decent human being in the Crapsack World of Black Lagoon, listens with sadness and horror rather than disgust at the coldly delivered "The Reason You Suck" Speech by Gretel, a little girl so traumatized by rape and torture with her twin brother Hansel back in Romania that murder has become the sole source of joy for them. He holds her in a tight embrace and weeps, begging her to accept the possibility that there is hope, and still a possibility of a new and happy life for a little girl like her. This act of sincere kindness, so alien to Gretel, was enough to move even a mass murderer like her to blush like a real little girl for the briefest of moments... and then one of the saddest moments of Does Not Know How To Say Thanks ever. Her version of thanks was to offer herself sexually to Rock, truly thinking that is the only way an adult will appreciate her in return.
