In Spidersilk, Mark finds himself visiting the theater with Mairis. Although it might seem like the two of them simply hanging out there is a lot of hidden elements in the description of the theater as well as the movie choices. If you notice, the theater is actually shaped like a spider web which hints at the spiders that were protection Mark. It is also a design of Ramses who plays a major role in the outcome of the story. That's not all though. Each of the movie titles shows an element in the book! Of course, Mark gravitates towards the movie that hints at being a master of Khi, which seems to show quite a bit about our leading man.
