He thought about what Rose said, and quite frankly he didn't buy it. He knew the real reason why she didn't broke those cuffs, she had already told him before he left the room earlier.
Robin narrowed his eyes as Rose spoke, again her hands were against his chin. It was clear signs that she wanted him to touch her back. What will Robin do? Cassie before...when they were on the roof top, he could feel it, she wanted him to be inside her. And before that, Rose kind of brought it out on the table.
"I never knew you for the type to start something then leave..."Robin said to Rose. He needed to clear the room, and what they needed to do was resolve everything now, if not, it might just cause them their lives in future battles.
Robin knew about Conner truthfulness, he takes it after SuperMan, of course, and like Conner, Robin takes after Batman, who...well you'll never really get the truth, but you won't get a lie either.
