Sheila and Ricks walk through

During their walk through, Ricki says he initially ran out his bedroom DOOR and down the hall when Sheila/Jaime started banging on the window that morning because it scared him. Ricki states Sheila said that didn't happen". She says on film, it absolutely didn't happen...at that time, but it's believed he came out sometime previous. So 1) something scared Ricki out of the room (by what and WhEN?) 2)This coupled with the phone cord statement 3)...and the phone interview make me believe they had absolutely discussed the murder betwixt themselves before the movie was ever an idea. Most important, is here they are both saying Rick didn't sleep through just to wake up and hop out the window. In lieu of Ricki's mysterious statement saying him and Justin came out, that's pretty interesting.
