Black Sheep 害群之馬,敗類

M：Considering this is Maria, I suggest you look in some place unusual.

SB：Well, Reverend Mother, I hope this new infraction ends whatever doubts you may still have about Maria’s future here.

M：I always try to keep faith in my doubts, Sister Bertha.

SM：After all, the wool of a black sheep is just as warm.

SB：We are not talking about sheep, black or white, Sister Margaretta.

Of all the candidates for the novitiate, I would say Maria is the least likely.
