The Brotherhood of Evil was always recruiting new troops to bolster their forces. They never actually expected the grunts to actually do anything meaningful, but they were good distractions when the Brotherhood needed to stall for time so a plan could succeed, or escape. They recruited from wherever they could find the willing. PMCs, trigger happy veterans, and even thugs who had enough of a reputation to satisfy their standards.
Training was brief. The recruits would run obstacle courses, build up strength, receive weapons training, and whatever it took to get them ready to be an expendable body to throw at whatever heroes had come after them. The Brain was certainly no fool however, and made note of any recruits who seemed to excel in all areas. Two in particular had been consistently topping everybody else, and were frequently around each other. So, the Brain had Madame Rouge watch over them in secret.
Unsurprisingly, it turned out that they were spies from the Titans. Beast Boy and Raven. The actual surprise had been how they were found out. The two had gone of in what they thought was total privacy, and were in the middle of sharing passionate kiss when Rouge blind-sided them both. Now they were at his mercy, trapped in the same prisons he had trapped the Doom Patrol back when he first encountered the Titans.
"Little. Green. One. Like. Many. Of. Our. Encounters. This. One. Has. Ended. In. Checkmate. For. Me. Though. I. Must. Congratulate. You. On. Discovering. Love. If. You. Weren't. About. To. Die. It. May. Have. One. Day. Rivaled. The. Love. Between. Mallah. And. Myself."
"I really never expected to receive congratulations on my love life from you, nor did I think all of you would find out before my friends."
Beast Boy looked the expressions on the Brotherhood's faces. Immortus was predictably apathetic. No doubt, he had been in this situation before with a different set of enemies. Rogue had a smirk of amusement on her face. The Brain, of course, had no expression, but he knew he meant every word. It was odd to think that an evil brain in a jar was a romantic at heart, but he recalled that the Brain had expressed genuine congratulations to Steve and Rita after their marriage. Mallah, for his part, seemed about as apathetic to the couple as Immortus, though he did notice him nodding his head along to the Brain's words.
He then turned to Raven, and she looked to be equal parts mortified and utterly infuriated. If her prison wasn't keeping her restrained, he had no doubt that she would have used her powers to crack the Brain's jar open over Mallah's skull. Then she turned her head towards him.
"When we get out of here, we're telling the others about us immediately."
"What. Makes. You. Think. You. Will. Es-"
An explosion cut off the Brain. The other Titans and the Doom Patrol had arrived. They'd fight the Brotherhood, rescue Beast Boy and Raven, and then they would face the judgement of their friends together.
