EPISODIUM
Rachel, Bailey and the team head to Yosemite National Park where a maniac brutally killed a mother and her two daughters, and while circumstantial evidence points to a local outlaw biker (guest star Douglas Bennett), Rachel constructs a different suspect profile -- one who feels remorse and might have sibling issues. Meanwhile, George's lingering substance abuse problem causes a dangerous embarrassment for Bailey and the VCTF just as an attractive Congresswoman (guest star Erin Gray, ""Silver Spoons"") begins an investigation of the unit, and she is most impressed by Bailey. Back at home, Rachel's budding romance with her brother's (guest star Raphael Sbarge, ""Message In A Bottle"") drug counselor (guest star Joe Flanigan, ""Providence"") hits a snag.
