"...That bitch."
It's a punch to the gut. She - she trusted a stranger, and look what happened. Valanda was acting nice. She was a friend in the middle of a hostile and confusing and incredibly fucked-up day.
And now Waltana is a slave. Because she accepted a damn pair of bracelets without thinking. It's a punch to the gut, a hot cinder of shame/anger/betrayal/despair. She wants to cry. She wants to break something. She wants to hurt Valanda.
She tries to leave the room. She can't. She can open the door, but then just - stops. She tries to pry off the bracelets. She can't. Obvious. She tries to open the window - she can open it, but it's too narrow even before she finds she can't even attempt to push herself through.
She throws the language-lesson illusion against the far wall and screams in frustration and tries to destroy her fucking owner's stuff, but it's all invulnerable or something. The best she can do is throw whatever's accessible into the hallway. She can't even shout or rave, unless she shuts the door and convinces herself very hard that she's only yelling to herself.
She calms down after a few minutes. She can send a construct to scoop up the stuff she threw, put it back in its place. Concealing the sheer rage she's feeling right now is probably going to be the hardest she's ever acted in her life. But if it keeps Valanda complacent until she can think of something - it'll be worth it.
