Giver chapter 16 stop the pills and have a new reaction.

okay so in the book Jonas didn't want to go back to the annex because the giver showed him a war with guns people fighting and blood. Also Jonas keeps sharing memories with Gabberial ( a small baby that Jonas family is taking care of), and Jonas decided not to take his pill.  my reaction is for the pill part like wont the counsel of elders or people watching them know and he will get in trouble.  My question is what happens if he stops taking the pills?
