Two current theories are:
- When they harvested Nixon's marrow they took all they could from him for it to be safe for him. However, it was on the low end of what they would have liked to be given to Faye. It could just be that it is taking more time because there weren't enough cells. If we get to day 40 or so and we still haven't engrafted they may take more from Nixon and top her off.
- They tested for all sort of viruses thinking if she had one it could be causing some immune suppression. Results showed positive for one but the levels were such that it could be the cause of her being slow to engraft or could not.
- There could be a host of other things also.
