At the beginning of this episode Cassie and Sam go into the lake house. There is a large American flag hanging on the back wall, the flag hanging vertically with the blue field of stars to the right. This is not the correct way to hang the flag vertically. The blue field is to always be to the left of the viewer, both flying normally (horizontally) or hung vertically. This can appear to be backwards to many people, which may explain the mistake, but also the series is produced in Canada which may be a factor.
