|“||She's always sorry... until she does the next thing.||”|
|— Polly to Betty about Alice[src]|
The relationship between mother and daughter, Alice and Polly Cooper is currently estranged, but they are trying to strengthen their relationship. However, since Polly has left town, their relationship is strained at the moment although she has allowed Alice to meet her grandchildren and spend time with them.
Presumably, Alice and Polly had a good relationship before Polly began dating Jason Blossom, the son of a family she despised. When Alice found out about the two she was furious and tried to break them up. She was thrilled when Jason's parents forced him to do so, despite her daughter's heartbreak, damaging her relationship with Polly.
Polly found out she was pregnant by Jason and they resumed their relationship and made plans to run away together and raise the baby because they knew their parents would not approve. On July 4th, the day Polly and Jason were to leave, Alice somehow found out and she and her husband secretly had their daughter forcibly locked away at the Sisters of Quiet Mercy group home for troubled youths and planned for Polly to give the baby up for adoption once he or she was born.
To cover up Polly's pregnancy, Alice and her husband Hal told everyone, including Betty, that Polly had a nervous breakdown when Jason broke up with her, and that was why she was sent to live at a group home, known as the Sisters of Quiet Mercy.
Leaving for the Farm
After learning that her mother received a letter from the Black Hood earlier in the day, claiming responsibility for the shootings of Fred Andrews, Moose Mason, and Midge Klump, as well as the murder of Geraldine Grundy in Greendale, Polly read a segment in the Register; entitled "Changes to Sweetwater River fishing regulations.
The next day, Polly told her family that she was leaving Riverdale to live at the Farm. She had already called to make sure they still had room for her. What Farm, Alice asked. Polly replied that it was the very same farm that she and Jason were going to run off to before he was killed. Before any rash decisions were made, Hal suggested that they all sit down and talk about Polly's sudden urge to leave. Polly explained that her need to evacuate stemmed from the Black Hood, who was targeting sinners. Betty did not believe that Polly is a sinner, but Polly countered that she was a mother that was carrying her cousin's babies, and decided that leaving Riverdale was the best way to avoid being targeted. Alice strongly objected to this, saying that Polly would leave Riverdale "Over my dead body" Polly replied "It might be over your dead body, but it certainly won't be over mine or my babies" She then left the room, and Hal followed her to try and talk her down.
Alice and Polly briefly appeared in Betty's anxiety induced nightmare. Polly entered Betty's bedroom to wake her up from her sleep and tell her that Santa Claus was down stairs. Downstairs, Alice, Polly, and Hal sat near the fireplace as Betty came down the steps. Moments later, Polly and Alice was dead, as was Hal. They had been murdered by the Black Hood who had disguised himself as Santa.
Coming Back for the Blossom Will
Learning that her children's late grandfather, Clifford Blossom, left a secret will, Polly returned to Riverdale for the reading. She surprised her mother and Betty with her sudden return home. But imagine Polly's surprise to meet her brother Chic, who she had no idea was staying at the house. After greeting Betty with a hug, Polly asked where their dad was at and if they would be attending the will-reading together. Which Alice had no knowledge of.
That night, following Clifford Blossom's Will-Reading, Alice prepared dinner for Polly, Betty, and Chic as they discussed getting the blood test done so that they could inherit the fortune they were promised through Clifford's will. Oddly enough, Chic refused to get his blood tested, claiming that he didn't know any of the Blossoms well enough to trust them, along with being triggered by needles and not wanting their blood money. Alice then came to Chic's defense and told the girls to stop pressuring him.
The following night, Polly went on a mini shopping spree with the money she inherited. She and Betty returned home to find that Alice had told Chic that he could take Juniper and Dagwood for a walk along Sweetwater River. The girls were immediately alarmed when Alice revealed that the twins were not home. Just as Polly and Betty began to panic, Chic walked through the front door with the twins unharmed despite their suspicions.
The next morning, Polly came down to announce that she was leaving again. However, she was not returning to the farm, rather San Francisco, which came as no surprise to Chic, who had already told their mother that Polly wouldn't be staying for long. As Alice went to say goodbye to the twins, Chic told her that it was a nice city to raise kids and that she should send a note from her new address once she got there.
