While Brad had been hauling Rico's ass upstairs and hung him on the wall, he had also texted Dirk. He had sent Dirk the video he had of Chad transformed into Rico's bondage suit.
"BING" the text chime on Brad's phone was probably Dirk's reply.
Brad threw himself back on Chad's bed and looked up at helpless Rico. He said, "Well, boys, that is probably your buddy Dirk replying to my text. I think I'll let him stew for a bit." Brad glanced at his watch, and looked out the window. He smiled, "Oh, he must be anxious, he's coming over right now."
When Dirk burst through Chad's bedroom door, Brad was nowhere to be seen. He laughed when he saw Rico trussed up in Chad, and then he read the words on Chad's and Rico's chest. He was still giggling, when he noticed Rico's eyes. Dirk turned to follow the eyes, and ZAP. Brad hit Dirk with a TASER.
