How is Aline, Solness' wife, portrayed in the opening act of the play, The Master Builder?

Aline Solness is portrayed clearly as a woman of perception and perhaps wisdom. It seems evident that she can see what's going on between Kaia and Solness, yet makes no comment on it. She does, however, stand up for herself when Solness makes the snide remark about Kaia being good-natured. This suggests that Aline is strong enough to take care of herself when her personal integrity is challenged, and wise enough to see that her husband's weakness for younger women isn't that kind of challenge - either that or she's given up fighting with him about it.
