I Lose Myself" is the sixteenth and final episode of the fourth season of the post-apocalyptic horror television series Fear the Walking Dead, which aired on AMC on September 30, 2018 in the United States.
Morgan plans to bring Martha with him to the truck stop, but she causes him to crash his car after he receives a distress call from the others, who have been poisoned with antifreeze in the water bottles.
With Martha dying of blood loss and a raging infection from her prior untreated gunshot wound, Morgan handcuffs her to a car door so that she can't harm anyone when she turns.
While their truckload of ethanol, the antidote, goes to waste due to bullet holes, Morgan arrives in time with a supply of Jim's beer to save everyone.
[1] Dino-Ray Ramos of Deadline Hollywood called the episode "a hopeful end to a rough season".
