When I was a child

That is something the script editor has ...

No I have Supporting Character Syndrome, I show up and give guidance and crack a few jokes before dying either stupidly or tragically or hilariously depending on the genre

I have some of the traits that they describe as MCS, but not others.

Just read about this in this article. Based on the description I don’t think so. Do you think that people who display this sort of behavior self-aware enough to know the behave this way. I worked with someone like this, and they’re an only child. She left the district because I think she felt like the article describes.
