In fact, Bridgette doesn't even remember who was present, except for her [sperm-donor], her mother (too shocked to move), and the butler (he got punched in the face trying to stop the [sperm-donor]). Additionally, while what was translated in this chapter depicts her mother resenting and blaming
Bridgette, which is how Bridgette interpreted what her mother was saying, her mother was actually resenting and blaming
herself (Japanese is a
pro-drop language, so what was "bad" and "at fault" was never actually stated). It later turns out the combination of shock of the event and depression from not being allowed to see or contact her daughter, compounded by her husband reacting by keeping her secluded in the house (good way to make a depressed person more depressed) results in Bridgette's mother making an agreement with an
unseelie (it drains something from her mother to the point of being life-threating), so that she can at least see Bridgette in her dreams. Per consequence, her mother eventually starts to confuse dreams and reality, evident in the woman's avoidance of fire (she screams every time that she won't be able to see [her]).
