Terri (The Hardest Part)

Terri is the mother of Casey.

History
Terri, Pam, and Ricky were in talk therapy with Sheldon and Violet because their three daughters, Casey, Lisa, and Jamie had made a pact to get pregnant together in high school.

The three daughters also came in to have take therapy together, to try to explain why they'd done it. Casey said she didn't think she should worry about good grades or college when all she wanted was to be a mom, Jamie said it was instant status, and Lisa said babies love you no matter what. There's a lot going on at her house, so her mother can't give them all attention all the time.

Ricky came in late to their joint session. She'd told Jamie she needed to pick up her brother, but she came back with Violet's book, saying Violet wasn't the right therapist for their daughters. She took Jamie and left.

Sheldon and Violet took Casey and Lisa to tour the hospital. Casey and Lisa by that point had read Violet's book and made several comments about it. Violet started to fight back, but Casey started having serious abdominal pain and bleeding. She was rushed in for an emergency c-section. Lisa watched as Casey's baby was delivered and said it wasn't what she expected and left.

Casey held her baby after his birth. Lisa had not come back. Jamie called and said she was giving her baby up for adoption. She felt her friends had abandoned the pact. Casey said he mom had only come by to criticize her and yell. She wondered how she'd do it on her own because she was totally alone. Sheldon told her she wasn't alone. She had Ben. She said she was scared and Sheldon said they could work on that.

Familial
When she found out her daughter was pregnant, she tried to force her to have an abortion. After her grandson was born, she showed up at the hospital only to criticize Casey and yell at her.
