Sara could have set her teleport to be from inside the building, but it seemed somehow rude to do so when she can walk out into public space instead. So, she finishes packing up, shoulders her bags, and takes the elevator down three floors to step out onto the pavement.
There's a little snow on the ground, but not enough to stop her from setting her duffle bag on top of one of her feet so she can get out her phone and request her port to Montpelier.
She disappears with a flash of negative-colour, and reappears somewhere else.
