The next week or so passes in a blur of tension. She tries to play games on her phone or read but she struggles to concentrate on them because she has to keep listening to make sure nobody is trying to get through the door or climb in the window. She spends a lot of time staring into space.
When she sleeps she sleeps badly and wakes in a panic every time until she can determine that nobody has snuck into the room while she was asleep.
She eats meal bars and drinks water though she unwraps the meal bars very carefully so they won't make too much noise and drown out the sound of somebody trying to get in.
The camping toilet needs to be emptied midway through the week requiring another Production.
Cousin Pierre sends texts several time a day to check up on her. He tries to make a little bit of small talk but she responds only briefly.
At one point he tries to broach the subject of having somebody bring her her schoolwork so she can keep up but she desperately doesn't want to think about school (so many people) and cries for two hours until she's too tired to cry anymore and doesn't respond to that comment.
She ends up with more furniture shoved against the door by the end of the week in hopes that it will let her stop panicking every time she wakes up.
Pierre isn't going to bring up the subject of esper awakenings with her because everyone decided not to get her hopes up, or upset her (and they are still mostly not bringing it up among themselves) and she's not going to think of it herself (that doesn't happen to boring people like her right? Her eyes are changing but she's not looking in a mirror and the reflection in her phone screen isn't clear enough to catch it unless the light hits it just right. (if she did notice she would not inform Pierre because then somebody would try to get in to see).
If she's jumpier by the end of the week because her desperate straining to hear anyone coming in picks up more sounds then well she's not going to really notice. (Esper hearing is very convenient and ignorable but only if you are actually capable of ignoring it instead of being on high-alert)
