David has shifted to look like a Professor at North Chicago University to steal answers to the math final. Upon leaving the building he gets a call from his sister [[Margo Lassiter|Margo]], who tells him that his brother [[Sal Lassiter|Sal]] has been killed and that he needs to come home. When David arrives, he asks Margo what happened to Sal, and she tells him that he was killed by [[Julian Duval]] and they plan to go to war with the [[werewolves]]. David next goes to see his ailing father, who is lying unconscious in bed. David attempts to dissuade his sister from jumping into war so quickly, and that they need to be smart and find out what really happened. But Margo dismisses him, telling he has no part in the matter. David decides to shift to look like [[Freddie Costa]] and visit the only witness to Sal's death, -- [[Ennis Ross]]] to question him about what he saw that night. When David begins asking him questions Ennis had already answer at the precinct, Ennis becomes suspicious and asks Freddie if he wants to hang around and wait for his Ennis' father to come home, not knowing that [[Nate Ross]] is deceased, David agrees. Realizing some thing is up, and remembering what [[Sam]] told him about [[monsters]] being able to be seen through mirrors and cameras, Ennis pretends to get a text and turns on his phone's [[camera]] which reveals "Freddie" to have a retinal flare. Ennis leads "Freddie" to another room where he quickly distracts him and pulls a gun on him, telling him there are [[silver bullets]] in the gun. This leads David to reveal himself as a [[shapeshifter]] to Ennis and proceeds to tell him how Chicago is divided up by five monster families, and that Ennis is in way over his head before making his escape. David later goes to the Duval Estate where he has a talk with [[Violet]] where he tries to get her to get her brother to have a sit down with Margo, which leads to them talking about their relationship when [[Irv Sokolowski]] attacks David, and kidnaps Violet. Sam, [[Dean]] and Ennis rush over to see what happened, and David joins them in there escape from the Duval Estate. After the Winchesters have been caught up with David being a shifter and the five monster families, the four team up and track Violet down by tracing her cell phone signal. They arrive at an abandon warehouse, and split up and search for Violet. David is captured by Irv who proceeds to cut him with his [[silver]] claw, this causes Violet to transform and break free and attack Irv. Before she can kill him, David frees himself and talks Violet down, who reverts back. Sam, Dean and Ennis arrive in the aftermath, where Ennis kills Irv in revenge for killing his girlfriend. The next day David and Violet are walking together on Duval Estate, when David questions why Sal's last words were "David, I'm sorry. I didn't have a choice." Violet tells him she doesn't know, and the two share a kiss before they go their separate ways. Later at the Lassiter residence, David is sitting with his father who awakens to tell him that his sister wants to go to war, and that he needs to stop her. David lays out Irv's silver claws on table telling Margo the Duval's are clean of any part in Sal's death, and telling her his intention of coming back to the family, for which Marog welcomes him home with a hug.
