Theory here: Q has said this has been planned for as long time. I had the thought today that maybe this means the posts were created ahead of time and in an order with events predicted logically. When an event shifts or does not happen, so a few pre posts are no longer needed, we get a Q&A or test posts as filler until the next pertinent drop post.
The above explains the watching a movie as well. The whole plot is lain out already and accounting for variables.
