What role does Parris play in Act 3 of "The Crucible"?

Act Three of "The Crucible" is where the action of the court trials actually begins for the reader/audience. We already know that Parris is going to be on the court's side because that will keep any suspicion off of him and keep it on the people who have been accused by the girls. In this act, Parris tries as hard as he can to discredit anyone who tries to go against the court. At times in the act, he even tries to push his way into pretending that he is one of the judges by questioning the accused -- he does this until Danforth finally gets annoyed by it and tells him to stop. This is the role that Parris plays in Act Three.
