If one thing is true about Georgia Miller, it's that she's gonna make a mess.

After a shocking revelation from her son Austin (Diesel La Torraca) left Georgia (Brianne Howey) off the hook in the months-long murder trial that dubbed her the "Mayoress Murderess" nationwide, she thought she was finally gonna get a moment of peace. Of course, that wasn't the case at all.

Season 3 of Ginny & Georgia instead ended with Georgia chugging milk right from the carton in front of Ginny (Antonia Gentry), who was quick to point out that her mom had previously said she only drinks milk when she's pregnant.

The cliffhanger ending came after Georgia tricked her estranged husband Paul (Scott Porter) into thinking she was pregnant earlier in the season, as a means of winning him back, only for the lie to leave their marriage truly irreparable.

"This was quite a messy season for Georgia," Howey tells PEOPLE. "Probably posing more questions than answers, truthfully."

As for the matter of her bombshell pregnancy, the 36-year-old actress herself doesn't even know what's next — or who the father is — because after all, "Georgia doesn't know."

"This is the one season where Georgia's just not in the know," Howey says. "Georgia's just not privy to these things."

"What I keep thinking about is the amount of tension that this is going to cause once Georgia realizes it herself," she continues. "Then the conversations that Georgia's going to start to have to have based on these results — with multiple people."

Of course, the baby could be her ex-husband Paul's, but it could very well also be Joe's (Raymond Ablack), since the two finally sealed the deal after two seasons of lingering tension on a night when Georgia was planning to run away from Wellsbury.

Regardless of what's ahead for her character, Howey says that the way the revelation unfolded, with Ginny pointing it out to her, was an especially fun twist. "I love that Ginny realizes it before Georgia. It's so good."

Gentry is more focused on what the potential new sibling for Ginny would be called. "What will we name it?" she asks in the joint interview with Howey.

"[Georgia] did say, in season 1, Barry would be cute for a boy," Howey recalls. "Little baby Barry."

Ginny & Georgia season 3 is now streaming on Netflix.
