When she got like this, when she lost control, even if it wasn't violent, River really missed Simon. She knew, logically, that he'd somehow gotten to get home. She knew he wasn't dead; she was certain she would feel it if he died, or would have, back when she still could feel other people's minds. She would have known. Still, that didn't stop her from feeling like she still needed him here, and wanted him here. Part of her thought that was incredibly selfish, the rational, genius part.
The rest of her did not care.
She was calming down, though. Was was helping. He wasn't Simon, and he wasn't Hannibal, but he was helping.
"I... think so. We can't... can't find her." She didn't like to think about that, about that woman being gone, too. Gone like Simon was, maybe. Without a trace. "I don't want them to shut me in Arkham."
Her tone got darker, then. As though she was insinuating she would not allow that to happen.
