While Fiona's planning a nice Thanksgiving, Monica's becoming more depressed than ever. Nobody can get Monica out of bed until Frank finally drags her to his brother Clayton's to help him claim his share of Grammy's money. When Monica fails to seduce Clayton (guest star KRISTOFFER WINTERS), she continues on her alarming downward spiral. Steve finally stands up to Fiona after Estefania and Marco have a tumultuous reunion. When Marco threatens to kill Steve for sleeping with his girlfriend, Steve agrees to surrender his identity so that Marco can stay in the country married to Estefania. Now, Steve can finally be with Fiona…or so he thinks. With Debbie worried that depression might be genetic, Frank realizes it may be time for Monica to get back on her meds, so he steals some lithium from Sheila. Things are finally looking up as the family gathers for Thanksgiving dinner… that is, until Monica slits her wrists.
