|“||Why don't I get Beth and we'll go out for ice cream? The last great idea that will ever be had in this garage.||„|
|~ Diane Sanchez|
Diane Sanchez is the wife of Rick Sanchez, the mother of Beth Smith, the mother-in-law of Jerry Smith, and the maternal grandmother of Summer Smith and Morty Smith, who first appeared in a memory projection in "The Rickshank Redemption".
She is voiced by Kari Wahlgren in the English version of the cartoon, and Germana Savo in the Italian version of the cartoon.
Diane is a young woman with has shoulder-lenght blonde hair and freckles. She wears a mint green tank top and wears a necklace and white pants and high heels.
While Rick was held in a Galactic Federation Prison, an agent named Cornvelious Daniel was sent into Rick's memories, using a brain link, in search of his memory of discovering inter-dimensional travel. Daniel witnesses a memory from Rick's past where he is a young man, proudly married to a woman named Diane, choosing to give up science after meeting another Rick. Diane walked into the room and was supportive, asking him how work was coming along, having heard "sci-fi noises". After Rick explained he was done with science, Diane suggested that he takes her and their daughter Beth out for ice cream, and Rick said that was the last good idea that'd ever be had in the garage. When Diane and Beth were heading to the car, an inter-dimensional portal opened above them and a bomb dropped down.
The explosion killed the woman and the little girl, depressing Rick and making him turn back to his life of science, and revealing the portal formula.
Daniel takes down the formula to achieve inter-dimensional travel, passing it on to his superiors. Shortly after the coordinates were downloaded, Rick revealed that the entire memory was false, and that the code was just a virus, that allowed Rick to gain full control of the brain link. He later told Morty, who had nothing to do with these events, that his backstory was "fake".
It should be noted, however, that Rick has separately been described as leaving his wife, and that they became trapped in a failed marriage, all of which are at odds with the flashback, as Rick appears happily married to Diane, supportive of his scientific study, and tragically dies in a science fiction mishap.
- "The Rickshank Rickdemption"
- In the memory during which Diane appeared, Beth Smith dies in the explosion with her mother, with both of their bodies being ripped apart, tipping the viewer off as a red flag that this story may be false.
- Rick maintains a similar appearance as a young man via Simple Rick in "The Ricklantis Mixup", supporting the possibility that Diane could be similar to her flashback appearance.
- In the episode "The ABC's of Beth", Beth ask Rick why would he made a clone of her so she can have some time for herself. He states that it might be something about her mother. This indicates that Rick possibly still loves his wife.
