Missy Percy (Chelsy BFF) and Thomas VanStaubanzee (close friend William) got divorced after two yrs for unreasonable behavior. But no actual indication of what the unreasonable behavior was ever was given. Unreasonable behavior in the UK really is the equivalent of irreconcilable differences in the US a kind of catch all. As for annulment- the CoE has all sorts of requirements for vows to be legit like using your legal name – which should have been Rachel and Henry those names were not used.
