[Even though this guy saw the supernatural powers already. He was at a loss for what he was supposed to be saying, his mouth twitching. Birdman kept saying that he and Rion were ill and delusional, and it seemed to illicit the sort of arms-length impersonal pity he was looking for right now.]
I am very, very ill. I am sure you have heard my brother, Birdman, talk about it. It is true. [chewing on lips]
