Actually, I posted my theory as a fanofmentalist, but they did not post it. I do not know why? I posted my first theory about walking steps of RJ in #5638. so, at that time, Patrick realised to Bertram's steps sounds. In se6ep3, Patrick told to Sheriff that he comes to Jane silently and Jane did not recognize him. I think Patrick has already known who RJ is and he is gathering some information, that's clues. If you remember when RJ saved Patrick's life, Patrick heard RJ's steps and, once RJ told Patrick a poem "Tyger, Tyger", RJ went away, we could hear it from his steps. But, suddenly, RJ touches Patrick from his left side with his hand and told about Crystine Frye. At that time also Patrick was afraid, because RJ came silently.
Any comments?
