Bo marries Megan’s sister Sarah, but she is kidnapped and believed killed by Carlo Hesser’s henchmen to keep her from testifying against him. While searching for Sarah, Bo is assisted by FBI agent Alex Olanov (Tonja Walker) who later turns out to be mentally unbalanced, and develops an obsessive fixation on Bo. When Bo begins dating Dorian's daughter Cassie (Laura Koffman), Alex flips out and tries to kill her. Later, immediately after Bo and Cassie are married at Llanfair, Alex shows up with a huge surprise—Sarah, alive and well. Bo leaves Cassie to reconcile with Sarah, but she actually dies from injuries caused by a car accident in November 1993.
