As if Lucy's romance with Stephen wasn't complicated enough, season 3 of Tell Me Lies provides another hot new love interest in the form of Costa D'Angelo's Alex. Based on Carola Lovering's novel of the same name, Tell Me Lies follows the messy relationship between college students Lucy (Grace Van Patten) and Stephen (Jackson White). Their problematic on-and-off romance ends up lasting eight years, with everyone around them affected by Lucy and Stephen's toxicity. Season 2 picked up months after Stephen blindsided Lucy by ending their relationship when she was a freshman.
