Deadly Misunderstanding - S7-E2
Continuity mistake: Throughout the episode, Jeff's hair appears very dark brown, almost black. In the rainy night sequence when he meets Melissa, his hair is dark black in the classroom—likely due to being wet—but shifts to a noticeably brighter light-brown tone once it dries. In subsequent scenes, it returns to its original dark brown colour. This variation cannot be attributed to lighting, as in multiple other interior scenes his hair remains consistently dark brown.
