Forget parting; season finales are such sweet sorrow, especially all these months later when it's time to remember what they wrought.

As summer shows make their return, here's some help with the memory jogging.

“UnREAL” (Lifetime, Monday). When we left the two at the end of Season 1, Rachel (Shiri Appleby) and Quinn (Constance Zimmer) had successfully wrecked what was supposed to be Adam and Anna's live wedding on “Everlasting,” sabotaging the creator of the series and Adam's chance of a spinoff series. Rachel and Quinn are back and changing things up by casting a black bachelor. (Are you listening, ABC?)

“Orange Is the New Black” (Netflix, June 17). To binge “OITNB” is to accept that you won't remember about 75 percent of what happened. But it was hard to forget that finale, which saw Caputo (Nick Sandow) blocking the prison guards' pursuit to form a union by accepting a promotion to run Litchfield. The move causes the guards to walk out; as a result, all the prisoners escaped to a nearby lake. Of course, there are also two busloads of new inmates arriving at the prison, meaning there are surely a few more characters to get acquainted with in the new season.

“Difficult People” (Hulu, July 12). The series, which stars Julie Klausner and Billy Eichner as two BFFs/struggling stand-ups trying to make it in New York City, ended with a Christmas-themed episode that found the two booking a coveted stand-up gig. Oddly (or sweetly?) enough, Billy has to back out because of family obligations and/or his desire to join the Gay Dad Mafia. The new season is sure to have the besties in even more colorful situations, considering its healthy dose of guest stars, who include Nathan Lane, Tina Fey, Debbie Harry, Amy Sedaris, Method Man and Joel McHale.

“Mr. Robot” (USA Network, July 13). It was the finale that had our internal dialogue going haywire. Elliot (Rami Malek) faced the reality that the man he knew as “Mr. Robot” was actually his long-dead father. Season 2 picks up with Elliot trying to recall what transpired in the three days during the massive off-screen hack that unfolded. And it seems E-Corp is still up to no good despite the financial hit it took in the finale.
