It's such an absurd attempt at reassurance that Greta almost laughs. "No," she replies, though there's no longer any recrimination behind it. It's just a statement of fact: none of this is 'fine.' Not their ill-advised attempt to visit, or Saoirse's resultant capture, or her own reaction. It's all terrible.

And so is Regan's insistence that she's going to fix this, somehow -- a different sort of terrible, but still. Greta shakes her head, sitting up a bit straighter. "You can't." That's not exactly what she means, but her signing is still rather basic. This is less about Regan's capabilities, which are hard to even judge given that neither of them know what they're up against, and more about the fact that Greta just won't have it. Regan could have died on the ostensibly straightforward walk from the cottage to the Gardens; she's not up for a bloody search and rescue mission. Neither is Greta, on her own, but she at least knows who she might ask for help.

She gives in and picks up her phone again. You're not going back out there. I need you here, to help with the children.
