She brought her prints home and then down to Cornwall?? That's so funny/pathetic!I think she took the prints to Northampton. In her "packing to evacuate London" vlog you can see them standing by her suitcases that she's taking, so I don't think she went back just for the prints. Still crappy of her to go from London to Northampton and then Cornwall of all places.
She still would have had to go to London to collect James in her car. I honestly wouldn't be surprised if she went back to get more stuff from her apartment when she was there. She went quiet on social media for a few days before posting in Cornwall.
