She's sad, tired, resigned and frustrated. She can see daylight through her cracked open chamber, but no matter how hard she tries can't get the right angle to see the sky. That frustrates her more than anything else does, most days. It seems almost cruel that she could fall so far as to literally have her innermost chamber laid bare to the open air and yet still not be free enough to look at the sky.
At a later point in her life, in memory of that helpless yearning and its eventual fulfillment, she takes the alt name 'Glimpse of Sky' when she needs an anonymous online identity. It seems a fitting choice to her.
