"Hazel, when you return to the palace you must come right to me because I need to have an important talk with you. One about being a queen, wife, and mother. It is important that you come listen to what I have to say as it will help you," said Tabitha.
Hazel needed the same conversation that she was not to seek out Tobias for all of her troubles. Before the wedding, Hazel should understand that Tobias was not her husband alone and she was sharing him with the kingdom.
Only when Hazel understood that would she be able to put up with the marriage she was getting herself into.
At this point, Tabitha didn't think she had to worry about Hazel not following her words because she didn't see yet that Hazel truly loved her son. Hazel seemed to be following her duty and since Tobias liked her, she knew to accept the proposal.
Tabitha had yet to understand who Hazel was because she had not seen much of Hazel's personality with her own eyes.
