He hasn't seen them overtly, they haven't talked to him, for months. Not that he is often alone now, there is always someone around him. There is a distinct lack of trust round here.
No-one else can see them, of that he is certain, he has seen them standing next to member of the crew who are completely oblivious to their presence. He still is aware they are there, he sees movement in his peripheral vision, a figure standing, watching him. Silent and almost still. Almost still enough that he could not notice them. Almost.
There is only ever one of them at a time. Sometimes it's definitely Franklin. Sometimes it's definitely Gloria. Sometimes when the figure is just a twitch of movement in corner of his eye he can't tell.
They don't appear in every room on the ship, the bridge, the observation lounge, the corridors, the infirmary. Most of the public areas of the ship. Never in his quarters for which he is eternally grateful. The idea of being watched while he slept is uncomfortable to say the least. The idea of Gloria waiting there…
He thinks, hopes, it's the AI. If it's not the AI then he's probably mad. It wouldn't surprise him, there is no way that he would admit anything publicly, but sometimes he thinks he's a little dissociative at least, and sometimes, when sleep has eluded him for a day or too, he thinks it goes further than that.
And they wait, in his peripheral vision, watching, waiting for him to be alone.
