Susannah, this is not about London vs, non-London, which is why I have edited the story. This could happen within the same centre; I have examples of this.

As far as defining a cure in sister 1; yes, she may be cured and that is an experiment that is currently running. Time will tell of alemtuzumab and HSCT cures patients of having MS.
