I understand, but consider the society she exists in. She needs to be the strong figure there for everyone and having all those annoying triumvirates trying to take her down, she needs that strength. And I do believe she trusts Marco, otherwise she would not have told him all that she is, she does not trust him now because he is still a kid (politically speaking) but she will come to trust him more on the years to come. She is a sad figure but she is extremely. She matters, but in the grand scheme of things...
