Erica fetches herself a duffel from the specified location and starts throwing in items. Anything she can find that was on their list, anything she sees she decides is worth taking even if it wasn't. When she's managed to fill up the bag, she grabs it, a sleeping bag and a guitar case. She hefts them, decides it is about at the acceptable weight range of 'as much as I can carry but no more', and kicks another duffel in Arthur's direction.

"I'll take these downstairs. You keep packing, you know where you keep things, I'll start ferrying things to the car."

She heads downstairs. How full is the back of the van? There may be some trunk tetris.
