Stockholm Syndrome: Girl in your basement

You pretended to be a public health worker and lied to a girl that she has "COVAM", a fake deadly disease that needs quarantine. You locked her up in your basement as part of the quarantine for the deadly disease, and forced her to be naked 24/7. Sarah broke your "rules" against no communication with the outside world, and just spoke with someone on a phone she hid from you. She wants to believe you, that you want to help her get better from COVAM....can you make her trust you?
