Surrogate?
Could of had her eggs harvested and implanted into a carrier. She did have that op a couple months ago and showed pics of her stomach bandaged?
This is plausible I suppose… if it were anybody but Cassy.
Announces a pregnancy despite drinking and smoking; you could suggest she’s not carrying the baby herself.
That said, she has NOT got a surrogate carrying her baby.
1: TL is not interested in having a baby with Cassy at all, there’s no way on Earth she’d have convinced him to go through any extended process.
2: Surrogates generally go through an an extensive selection process and get-to-know the Intended Parents.
Find it incredibly unlikely anyone selfless and generous enough to bring a baby into the world would meet Cassy and think she’s a deserving mother over couples that are desperate and have waited almost a decade.
