She'd noticed Ava's absence, after the return. It wasn't out of the ordinary - Helena had thought it best, if she needed to heal. But it doesn't mean she doesn't worry in the process, wonder how she's doing. She has her Mr. Smith, of course (certain people keep her well informed as to the happenings of the ship), and hopefully he's been a great comfort, along with all of her other friends. That said, perhaps Helena is too inclined to dwell on a few things. Maybe she's presuming, still unable to shake the idea of Ava's awareness coming from a particular place.

So, with some time passing, when Ava's probably decided to come out again, her phone will get a message.

Hello, Miss Ava. This is Helena. Do you feel like talking right now? It's all right if not.

The voice to text leaves things a little more formal, but such is correct translation.
