Monday's Major Crimes finale will attempt to close the book on a major chapter of the show. 

As Capt. Sharon Raydor (Mary McDonnell) & Co. try to find the killer who attacked Rusty (Graham Patrick Martin) to prevent him from testifying against serial rapist Philip Stroh (Billy Burke), Rusty will have his day in court.

"I felt like it was time to put Rusty on the stand and that it was time to see what Sharon's tutelage had accomplished," creator James Dufftells "It was time to help get a little closure to the ongoing emotional arc we have been dealing with between Rusty and Sharon in the matter of Philip Stroh. It doesn't mean [Rusty's] out of the woods. It just means things are looking up for him."

Indeed, while Rusty has no more run-ins with his attempted killer, he will face off against Stroh's bulldog of an attorney Linda Rothman (guest star Jeri Ryan). And as you can see in the exclusive sneak peek clip below, Rothman will go to any lengths to discredit Rusty as the prosecution's material witness.
