In the upcoming episode of "The Last Man on Earth," eager fans will learn what Todd (Mel Rodriguez) has hidden in the garage.

Episode 4 left viewers wondering what secret Todd had hidden away in there, described in a promo for the upcoming episode as "out of proportion with the world's small population."

The wait for answers may already be over for those following the season closely. In the next episode, titled "Crickets," Todd's secret will be revealed.

Though the description of the garage's contents remains somewhat mysterious, it may have something to do with Phil's (Will Forte) brother Mike (Jason Sudeikis).

Mike, who is an astronaut sent into space before the apocalypse began, has been stranded in his space station. Though he can look down on the events taking place on Earth, it seems he has no way of getting home.

Still, a big reveal seems to be on the horizon, likely upending Mike's situation.

In the last episode, according to Vulture, Phil was incarcerated by his fellow compound dwellers, but ended up out-punishing them by imposing an even stricter sentence upon himself. But once he saved their new community from a fire, the group quickly let him go. He is once again a free man within the new compound.

Only in the final moments of the episode did viewers learn that Todd has a secret hiding in his garage, despite claims by his lover Melissa (January Jones) that he is a good man, who simply acts weirdly.

Phil will be on the case to reveal the secret in the next episode.

Episode 5 will air on Fox on Sunday, Oct. 25 at 9:30 p.m. ET, according to TV Guide.
