Nothing is known about Primo's life before or as the outbreak began except that he may have lived in or near Washington D.C.
Several hours after the pre-dawn raid led by Rick Grimes on the Savior outpost, Primo tries to escape on a motorcycle, which Daryl Dixon recognizes as his own. Rosita Espinosa shoots Primo off the bike and Daryl tackles him as he tries to flee and beats him into submission. Daryl demands to know where the Primo got the bike. As Rick holds a gun to the Primo's head, a woman speaks through the man's walkie-talkie, ordering Rick to lower his gun. "We've got a Carol and a Maggie. We're thinking that's something you want to chat about," the woman says.
Primo remains captured by Rick's group and his release is negotiated for Carol and Maggie's release from the Saviors. Paula, the woman on the radio with Rick, denies the offer, citing that giving two people for one was not a good trade for them. Rick tries again, but Paula simply asks for time to think it over while she takes her two hostages away.
Once Rick's group arrives at the Savior rendezvous point with Primo in tow, Carol and Maggie reveal that they had killed their captors. Primo is horrified by the realization that so many of his friends had been killed over the course of one day. Primo is then questioned regarding Negan, in which he replies "I'm Negan, shithead", which prompts Rick to execute Primo in front of the others without hesitation.
