Sagan, slightly exhausted from all his movement, proceeded to try to explain his situation to Kate. However, as nobody had actually taught him sign language, he didn't do a very good job of explaining. He started making several strange gestures to Kate, flailing his arms around wildly. He wasn't sure if Kate would be able to interpret the message, or even worse, what if she misinterpreted it? God knows what message she could possibly extract from the series of gestures, but considering the circumstances, it was highly unlikely that she would be able to interpret it correctly. After he finished explaining, he changed his facial expression into what could only be a "did-you-get-that?" face and made eye contact with Kate.
