On the way back, however, they find Steffy, whose ATV had crashed while she was trying to chase after Liam. Steffy ends up in the hospital.
Determined to keep Liam and Steffy together, Bill cons the doctor into changing the MRI results to make it seem like Steffy had a blood clot and any serious negative emotional impact would cause the clot to burst. The tactic ends up working for a while until a suspicious Katie takes the MRI results to her doctor and discovers that Bill changed the results. Katie, who had escaped froma tower that Bill locked her in to keep her from telling Liam the truth, manages to tell Liam all. Liam feels betrayed by both Steffy and his father and reunites with Hope.
