In the latest promo of the upcoming episode, the old folks of Springfield reminisce their past loved ones. Grandpa Abraham Simpson sees his dead wife Mona, and says, "I thought you were gone?" To which she replies, "Nonsense Abe! I didn't leave you , and I am never going to leave you."

"That doesn't sound like the Mona I knew?" says Abe, to which she replies, " I am the Mona that lives in your memory, with all the anger turned to honey by nostalgia."

Grandpa and others at the old-age home are happy. However, the Mona, that Abe sees is not real. She is in fact a drug-induced hallucination. Meanwhile, Homer, Marge, Bart and Lisa will try to rescue the old folks, who are taking a drug that allows them to relive their happiest memories.
