Bonus points to whoever shouts out Robin's identity.
Starfire froze. 'Robin's mother was in trouble?' She couldn't fault him for leaving. 'But, why was Nightwing so worried? They must know each other. Robin grows up to become Nightwing.' Frustrated, Starfire returned to Titans Tower.
Cyborg typing furiously at the computer, greeted her.
"Friends, I have heard a most puzzling exchange between the 'Nightwing' that broke into our tower and a woman he called both 'Kate' and 'Batwoman'." Instantly all eyes were on the Tamaranian.
"I've got confirmation that 'Nightwing' really is Nightwing. And he's Robin's older brother." Cyborg said.
"So, if this Nightwing, dude is Robin's brother and he says Robin is missing, why hasn't Batman shown up?" Beast Boy asked. No one had an answer.
"This conversation you heard, Star. What happened? Tell us everything you remember." Cyborg coached.
"Nightwing greeted the woman, calling her 'Kate'. She referred to him as 'Drake'. Then he asked if she preferred 'Batwoman'. He told her that we did not know where Robin was. They spoke quickly, and they finished each other's sentences. They concluded that Robin left on his own."
"Which we already knew!" Beast Boy called. Raven shushed him.
"Nightwing said that Robin may have left with his mother." Starfire added.
"Why would that be a problem? It's his mom." Beast Boy said.
"Maybe his parents don't like each other." Raven said. Starfire frowned.
"Are not the 'married couples' in the 'love'?"
"They might not be married. I mean, can you picture Batman as a family man?" Cyborg said.
"That's beside the point," Raven said shortly, "The most likely place for Robin to be is with his mother. So, who is Robin's mother?"
"Catwoman?" Beast Boy suggested, "Wonder Woman? Superman?"
"Use your head, BB" Cyborg said, "Superman and Wonder Woman are both in the Justice League. And Catwoman lives in Gotham. Any way you slice it, none of them can be Robin's mother, or else Batman would have already found him.
"What if… What if Robin's mother is a villain?" Raven suggested.
