Arianna Hernandez

Arianna "Ari" Maria Hernandez (portrayed by Felisha Terrell (2009) and Lindsay Hartley (2009–2010) is Rafe's younger sister and older sister of Gabi.

Arianna is the manager at the Brady Pub. Sami first thinks that she is Rafe's former lover. Arianna does not approve of Sami and Rafe's relationship, warning that it might end in disaster like his previous relationship with Emily Hudson. Arianna's fears intensify when she learns that Rafe wants to adopt Grace, believing that he is trying to recreate the family he lost years ago.

Arianna and Brady Black have a budding relationship, one that started off cool but has blossomed into mutual attraction. Arianna ends her relationship with Brady after his grandfather Victor Kiriakis finds out she deals drugs. In reality, Arianna's mysterious connections to local drug dealers are related to her undercover assignment from Roman Brady and the Salem P.D. After Victor tells Brady she was a drug dealer, Brady confronts her and she tells him the truth. Their relationship suffers further difficulties due to Arianna's suspicions about Brady's close friendship with Nicole DiMera.

In July 2010, it was announced that Arianna's portrayer, Lindsay Hartley, would not have her contract renewed with Days of Our Lives. Her exit storyline, presented in the October 26, 2010 issue of Soap Opera Digest Magazine, surrounds Arianna's interaction with EJ DiMera following his assault and shooting.

Arianna promised to help her friend, EJ DiMera, find out who shot him in October 2010. Discovering evidence that could incriminate Sami Brady for the crime, Arianna made plans to meet with EJ at the Pub. However, when she arrives at the Pub, she finds Sami's son there, and he confronts Ari with what she is doing to his mother. Arianna becomes upset and runs out of the Pub, and ends up getting hit by a car and being the victim of a hit-and-run accident. She is taken to the hospital and undergoes emergency surgery. After the surgery, EJ visits in order to share her findings. Unfortunately, she suffers cardiac arrest. On October 27, 2010, a priest is called to administer last rites and shortly thereafter, with Rafe and Gabi at her bedside, Arianna succumbs to her injuries, unable to let EJ know that Sami shot him.
