Robin nodded at the mention of this brother. He still was not sure how he felt about sharing a sibling with Gisborne-- well, that wasn't entirely true; he hated it,-- but after growing up without any family, the idea was rather appealing.
However, barring the man being pulled into this time as they had been, he would never know. Biting his lip at Much's question, he replied, "I rather hope that they're somewhere else, but if not..." He gave him a sad smile. "They'd long ago have lived out their lives, same as we would have done." He had to chuckle at the thought of their big man friend in this world. "Can you imagine Little John here? He would either love it, or hate it." It was hard to picture John outside of the forest; he had been there for so long.
He glanced at Much, relieved that his friend was apparently joking about being told to shut up. Robin knew he needed to be more patient, but sometimes that was easier thought than done. But then, he found himself laughing again. "If so, I'm not aware of it. And a human adversary might be preferable to what else is going on, hey?"
