Someone asked about the Hospital Bills, since the UK has NHS.
At one point in collage we had a reading assignment that involved the NHS in the 1970s. During this time London had a bit of a staffing and room shortage in hospitals. If you wanted/needed a room to yourself you had to pay out of pocket and use 'private rooms' in some places.
William had to be placed in his own room because of Krane. With it unknown by staff who attacked who the individuals involved had to be separated and most hospitals have rules that they can't be visible or have easy access to eachother.
This happened a few times in real life, especially when the police/a crime was involved.
The bill isn't big (think under $250 US today) but for people in dire straights thats a lot of money.
