Could Allirea use her phasing as a signalling mechanism? For instance, someone she’d met could reasonably often check if they can remember her existence (if doing it mentally is prohibited by the power, then have a PDA or something that sets off an alarm with the word ‘Allirea’ every five minutes) and if so, take some action.
This is plausible in principle.
The relevant question here is, I suppose, whether Allirea’s phasing immediately affects everyone on earth who knows her, or not. If the former, is there a lightspeed delay?)
I’m not planning to figure in a lightspeed delay on account of that being a pain in the neck. It propagates immediately (or at least over the course of the time it takes her to (un)fade). And it’s “fading”. “Phasing” is what wolves do when they shapeshift.
There would be little to no plot-relevance either way; it would just be incredibly amusing if the available method of FTL signalling involves someone conditioning on whether or not they can remember Allirea’s existence.

It shouldn’t matter much either way: the diameter of Earth is only 0.04 light-seconds.
