Final answer:
Ingraine could be upset due to the death of her husband, anger towards King Uther, concern for her daughter, or Merlin's prophecy.
Step-by-step explanation:
Ingraine is upset between hearing about the death of her husband and after she is married to King Uther for several reasons, which could include mourning her husband's death, being angry at King Uther for his advances, being anxious about her daughter's safety, or being troubled by Merlin's prophecy.
These emotional states are common in narratives where characters face sudden and impactful changes to their lives, such as the loss of a spouse or the threat to a child's well-being. Additionally, the feelings of rage and betrayal that come with forced remarriage, especially in a medieval setting where women had limited agency, contribute to the complexity of her emotional turmoil.
