When the aunt enters the room, the setting momentarily shifts to seem less creepy and more dynamic. Before her arrival, the conversation with Vera (the niece) is filled with a haunting sense of loss and tragedy regarding the open window and the lost family members. Vera's somber recounting creates an eerie atmosphere, but when the aunt enters, her bustling presence and cheerful apologies disrupt that mood. The room transforms from a space heavy with grief to one that feels more lively and engaging, reflecting the aunt's dynamics and her ability to change the tone of the conversation. Thus, the correct response is:
It seems to become less creepy and more dynamic.
