@Dogday88 – i don’t think appearance and character is the issue.. i think it is more that Marigold is just too Vain to date lord splended humility. vanity and humility are effectively complete opposites, and both MHN and LSH take their respective sides to extremes. marigold is so vain she gets enraptured by her own reflection, in much the same was was narcissus in the greek mythology, while Lord Splended Humility is so humble he refuses to even show himself or talk to anyone in order to avoid failing to be humble. Florence is likely much less vain than Marigold is, and thus would be able to relate to LSH on a much deeper level.
