Riverdale #10

The principal annouces a problem with mono among the students. All of them are required to be tested for the disease and put into the gym if they are infected. There is supposed to be a play put on by the students, The Crucible, which is about the Salem Witch Trials and how people behaved during them.

The ones in the gym just happen to be the main cast and the backup group has no signs of the disease which causes the students in the gym to start questioning each other about who got them into that mess in the first place.

It's very much related to the theme of the play and is done rather well.

They find out who was behind it all and Cheryl, who is infected, kisses the boy who caused the problem on purpose to get him infected.
