I assume she's been giving that talk to the students over and over again in her classroom. That's where she is the "teacher". But this the tournament where she, in a sense, assumes the role of coach[1]. So, while I too am not comfortable with that kind of talking to a kid, I suppose a little harshness was justified. Because the kid KNOWS that two seconds isn't enough. Because they HAVE been working on his thinking habits. So if he is forgetting the basic rules they have been discussing for this long, then a little harshness is perhaps needed.
