The Chocolate War Chapter 17 Summary

It's the eleventh day of the chocolate sale and The Goober, like everybody else, is waiting for Brother Leon to call Jerry's name in the roll call.
Finally, he gets to Jerry.
Jerry says – "No!" (17.16).
The Goober feels like his eyes are documentary cameras. He looks first at Jerry, then at Leon.
Leon is obviously utterly surprised by this recent turn of events.
Leon says Jerry's name again.
Jerry says, "No. I'm not going to sell the chocolates" (17.20).
And then everyone is very, very quiet.
