Ben calls the evil Ben "Derek" for the first time. He seems to be his evil twin brother. Annie gives Gregory a bill for liquor that Olivia apparently signed, what makes Gregory tell Olivia that he's sending her to rehab. Olivia leaves a suicide note to both Cole and Caitlin, so Cole rushes to stop her before it's too late. Casey arrives at Ben's place, where Derek tries to find out what is Casey's name before they figure out that he doesn't know who he is. Later, Derek threatens to kill Meg unless Ben gives him the passwords to his financial files. While transferring Tim to Cedar Oaks, the staff discovers an ad for Derek's place. (thetvdb.com)
