Cassidy was just practicing her aural and sight shields at their highest strength to see what she could do, really. That was why the door opened and the only thing to be seen was a pot and mug floating to the counter. The pot smelled a lot like hot chocolate and mint.

Nothing to see here but chocolate for you, Karla. Really.

Cassidy is not at all hopingpretending that she is really invisible to Karla of all people.
