Another attempt to summarize my perspective that will only seem inaccurate later:
At this point, it’s seeming as though the only notable difference between narrative and linguistic subjects (fictional characters and real people) is one of physicality in this linguistic, physical realm (lacanian ‘reality’): we linguistic subjects have bodies, narrative subjects don’t and may or may not ever. But, in discourse–communication via representations that pretty much constitutes all media by definition–physicality is what’s precisely not needed, worked around, obviated. So, the distinction between the subject who has a body and the one who doesn’t, at least in how they’re treated, how their identities are socially understood, how they are defined in discourse, doesn’t amount to much.
Especially since we’re also getting around the lack of fictional bodies by making our fictions more realistically interactive in various ways, such as gaming, VR cinema, and even ‘Choose Your Own Adventure’ YouTube series.
