I may be failing a class in my master's program. Should I mentally prepare for dismissal?

It's the final week of my first semester of gradschool. I have 2 A's and a B- that may become less than a C. I finished my undergrad with a 3.7, so I'd hope it'd be reasonable for the board or whoever's in charge to think "hmmm, well it's not a pattern for this student to do this poorly," and have some leeway with it. It's also a "Special Topics" course where the class topic and professor change each semester.

I know about the warning > probation > dismissal pipeline for semesters that you finish with a GPA below 3.0, but there wasn't any information on what happens if you specifically fail a class. As per that guideline alone, I could finish this semester with less than a 3.0, get an A and a B next semester and have a 3.0 or higher. If that's the case then I'm fine, but if <C = auto-dismissal then I'll start packin my bags lol.
