Elaborating a little more
>we know it's none of the other obol members
because Trigger is rushing them to the dorm so that they can tidy Flora's room up after she said that she would go there more frequently (that trigger thought that Flora said she's coming back for good)
>it certainly isn't Veronica
Veronica probably has Flora's number, but they hate each other and she wouldn't send something like this to Seed
>seed isn't close to anyone else
Seed is a loner, and she's only really close to the Obol members (even then not that much) and Phaethon. Phaethon is in the scene and obol is occupied with something else
>Senior
is the most likely person to be sending this message, because it's reacting to Flora laughing (probably the first time Senior saw Flora show an emotion that isn't dread/fear/anger) and her having close friends.
>another AI
I wouldn't discard the possibility of another AI appearing in the story, because it happens right after Flora finds out she's from Helios Academy and Fairy also appeared after Phaethon's PC crashed because of the hack. The AIs could be spying on Helios Academy students. but this is very unlikely given the context, but not impossible
