There's no closeups on Kay during the hearing segments. Whenever we see her she is sitting or standing behind Michael and is virtually expressionless throughout the entire thing. I suppose we sometimes like to imagine things just in order to generate discussion where there's little or no cause.

Anyway, Kay's appearance at the hearings was not a threat to their marriage since it was really already over. Even if Kay had not already decided to leave...they no longer had a marriage. Especially once Kay had that abortion...even though she had yet to tell him about it.
