Caleb and I were sitting in the playroom seconds ago in silence, when Caleb casually mentioned that he made Tok watch 2girls1cup and Tok had reacted as expected, with disgust and nausea. I snapped my head to look at him and demanded why he had said that, specifically had he said that because he was looking at my screen. He said no, a bit uneasily under the assumption that anything on my screen had to do with the video. In fact, I had been looking at this picture just as he told me that, unbeknownst to him.
