Fans of “Mr. Robot” might be a bit fuzzy on plot details — since it’s been two years since the USA drama’s last season.

When shows have long gaps between seasons, the mere act of keeping up can turn a hobby into a chore — especially with over 500 shows competing for your attention.

Here’s a handy guide to how some returning fan favorites ended their seasons — and what to expect going forward.

“Fresh off the Boat”

(8:30 p.m. Sept. 27 on ABC)

Last season threw a few monkey wrenches into the Huang family. Eddie’s (Hudson Yang) cultural exchange program was cut short when he crashed a bus, resulting in his banishment from the program, but the season ended on a high note of family harmony. Will that stay the same in Season 6?

“Hawaii Five-0”

(8 p.m. Sept. 27 on CBS)

Season 9 of the long-running procedural ended when a gunwoman open fired on the Five-0. Were McGarrett (Alex O’Loughlin) or Ortega (Jorge Garcia) hit?

“Poldark”

(9 p.m. Sept. 29 on PBS)

Season 4 of the BBC/PBS period drama ended on a dramatic and tragic note, with Ross Poldark’s (Aiden Turner) former flame Elizabeth (Heida Reed) giving birth to a baby girl before dying. In the fifth and final season, Ross and his current love Demelza (Eleanor Tomlinson) aim for a simple life — but the universe has other ideas.

“God Friended Me”

(8:30 p.m. Sept. 29 on CBS)

No show ever sounded more like a one-season concept, but this dramedy about an atheist who gets a Facebook friend request from “God” continues onward. At the end of Season 1, it was revealed that Miles (Brandon Micheal Hall) wasn’t the only one chosen as a “friend” for the mysterious account as new character Joy (Jessica Lu) was introduced — and his girlfriend Cara (Violett Beane) left for Paris.

“Mr. Robot”

(10 p.m. Oct. 6 on USA)

Season 3 ended (in 2017) with Elliott (Rami Malek) making peace with the mysterious Mr. Robot (Christian Slater) and vowing to bring down the world’s true villains. He learned that Mr. Robot is essentially the other half of himself, and that they must work together. It was also revealed that Phillip Price (Michael Cristofer) is Angela’s (Portia Doubleday) father.

“Riverdale”

(8 p.m. Oct. 9 on The CW)

The end of Season 3 revealed that Alice Cooper (Madchen Amick) vanished and that her real long-lost son is an FBI agent working to take down cult leader Edgar Evernever (Chad Michael Murray). There was also a flash-forward to Archie, Betty and Veronica around a fire, covered in blood and agreeing to go their separate ways — with no Jughead in sight. Season 4 will fill in the gaps that led to that ominous future, while the death of co-star Luke Perry, who played Fred Andrews, will be addressed in the season premiere.

“The Marvelous Mrs. Maisel”

(Dec. 6 on Amazon)

The end of Season 2 found Midge’s father Abe (Tony Shalhoub) wanting to quit teaching at Columbia and return to activism, while Midge (Rachel Brosnahan) accepted singer Shy Baldwin’s (Leroy McClain) invitation to join his six-month tour. Midge’s love life was in disarray; Benjamin (Zachary Levi) wanted to marry her, but she spent the night with her slimy ex Joel (Michael Zegen).
