She stabs the man with his own knife in self - defense, initially leaving him for dead . After informing Sara and Morgan of what happened, the three return to the site of the attack, only to find the mechanic missing .

Though Finn originally thinks it may be the work of a copycat, her old colleague and recent love interest, Daniel Shaw, confirms that his partner has gone missing, and it may be the work of the Gig Harbor killer - whom D.B. and Finn supposedly apprehended in Seattle .

"Girls Gone Wilder" has Finn accompany Sara and Morgan to a forensics conference when a shooting occurs .
