It’s very possible that Hollie’s animosity is directed at ‘hands-off’ staff (who she perceives as making the decisions and not knowing Archie) and not the ‘on the ground’ staff. This is often the case, ime.
There’s no way hospice staff could care for him. He needs senior specialist ICU staff, and lots of them. There’s no way he could be moved. He wouldn’t make it out of the room, sadly.
I wonder if she just can’t face going home. That would be completely understandable. And I wonder if being with Archie is too hard to bear, too. For all her self-deception, it must be hard to see him as he is and keep going. Maybe all the media stuff is a way of helping him without having to confront it so much. After all, there must only be so much you can say, or do, with a person who is so clearly no longer there. If she was with him more she might not be able to go on convincing herself he’ll wake up.
