How we cite our quotes: (Chapter.Paragraph)
Quote #7
"Not very loyal," he remarked.
I picked it up. "Not very polite to stop my servants and read my letters." (18.65-18.66)
Mary is a bit of a hypocrite here. Just about ten minutes ago she read the queen's mail and told her uncle all about its contents. Doesn't feel good to be on the other side, does it, Mary?
Quote #8
"I knew you would tell your uncle or your father, or the king. […] I knew you would betray me." (22.30)
The queen doesn't take it personally when Mary betrays her; she understands that Mary has to be loyal to her family first—even if her family is a nasty piece of work. That's why she can still treat Mary like a human, and almost like a friend.
Quote #9
"She's my sister," I said passionately.
"And I am your queen," she said, like ice. (29.26)
When we said the queen doesn't take betrayal seriously, we meant it only regarding personal matters. When Mary spills the beans about the queen's marriage troubles, Katherine brushes it off. But when Mary exposes a secret code from Spain, that almost amounts to treason in Katherine's mind.
