I see the videos affecting their robot psychology, and it does make sense that robots would get instructions from other sources than just humans speaking words to them. However, I don't see it as manipulating, which indicates a specific intent to cultivate and/or direct action. It is more a layering of video activities onto the original programming, which created a modified [new] programming. It resulted in a powerful, successful team, so it is logical to them the programming is the goal should continue.
I wonder where serendipity is in the Dramatica theory. The Mirriam-Webster says, "....I once read a silly fairy tale, called 'The Three Princes of Serendip': as their highnesses travelled, they were always making discoveries, by accidents and sagacity, of things they were not in quest of…." Walpole's memory of the tale (which, as it turns out, was not quite accurate) gave serendipity the meaning it retains to this day."
