Gwen is reporting for her local TV station as Zack is about to climb a tree to save a bird. Gwen is surrounded by a number of fellow students, including two behind her at the right of the screen. One of these is wearing a zipped-up jacket and glasses, the other an unzipped jacket and no glasses (and different hair). In the quick cuts between Gwen with her microphone, and Zack about to climb the tree, the wider shots have the zipped jacket and glasses closest to Gwen, while the tighter close-ups have the unzipped jacket and no glasses nearest to Gwen.
When Gwen is trying to convince Spence to help her TV-news-reporting career get started, there is an optometrist's eye chart on the wall next to the door behind her that appears backwards (i.e., a mirror-image).
