Those who look through the communicator on her dresser find Yvaine heading to sit on her bed and chant. It's the lighting spell Zelgadis was teaching yesterday. She keeps count of her attempts to find a rhythm in the work. It steadies her thoughts. On her fifth attempt, a tiny globe hovers for a second.
Yvaine smiles and the spark disappears as she glows faintly. She tries again, but this time only her light is present. She frowns, unsure if that is drowning out the globe; Yvaine suppresses it consciously. When the result is the same two attempts later, she pauses - and sees the communicator's camera pointed at her.
"Fuck," she says very quietly, and turns it off.
Action 1 - Sector 4, Her apartment at Clocktower Estates
Yvaine alternates between sitting and pacing, trying to think of what to do about anyone who did see. If your character and she have been friendly, she'll probably allow them to discuss this in the apartment. Or anything, if they just want to visit her. They don't have to have seen the video.
Action 2 - Sector 4, Quatro Park
Regardless of whether they saw the video, anyone can approach her as she calms her mind at: the park, heading to the park, or heading from the park. It's hopeless to worry too much, and that will get in the way of proper thinking too.
