In the hospital right after telling Patrick that Partridge said 'tyger, tyger' before 'dying'....she goes on to say, isn't that what RJ said to you??????  When did Patrick tell Lisbon.....in 2:23, RJ kills the students and recites the poem to Patrick, however when later talking with Lisbon about it, he specifically says RJ said nothing.  He keeps this bit of information secret.....to himself.

Did  I miss a subsequent episode when he told Lisbon???  I don't rememmber him ever telling anyone about the signfiicance of that poem, or tyger, tyger.   How could Lisbon know this information......did she just slip...is she involved???
