Who is Doctor Condor's wife from Beware of Pity and what is their importance?

Klava, Doctor Condor's blind wife, serves as a supporting role to that of Edith. Both women are disabled and both women have some of the same characteristics, such as a propensity for drama and overreaction. However, unlike Edith's outbursts, which are generally self serving, Klava's outbursts are often in protection of her husband. It is clear she adores her husband and that he, in turn, adores her as well.
