It has been heavily implied Abraham will be the Walking Dead character to crossover into Fear the Walking Dead.
Yet even more interesting is that Walking Dead showrunner Scott M. Gimple has joined season 4 of Fear as an executive producer.
Despite the fact that Fear started airing five years after Walking Dead, the new drama actually takes place back at the beginning of the zombie apocalypse.
There were a few mentions of Houston and heading up north, making the Texas city a likely candidate for season 4.
