Regan nods slowly. She wants to believe that Greta's right. She wants to believe that Anne won't suddenly turn against her — against them — and and leave Greta heartbroken, with Saoirse and Regan there to pick up the pieces. And that's not how it happened with Thomas, by any stretch, but it's the worry she still has.

"I guess, yeah," she agrees, still keeping to softer, uncertain language. Like she's afraid of committing to one decision or another, in case it goes south. And maybe that's exactly what she's afraid of. Anne, to Regan, is an outlier, an unknown, and trusting her in any capacity, but especially with Greta's happiness, is scary. But if Greta trusts her, then maybe Regan can, too.
