I'm not a Mark fan, but I think he simply got lucky this year. Do I wish Maks would get lucky with a partner like that? Absolutely! Unless there's something about Katherine background that I don't know - and all I know is that she took ballet, which is true of lots of girls - she's not a ringer. Sorry, I'm just sick of that word now after so many seasons.
In spite of myself, once again, I enjoyed their dance. Who knew a classical/opera singer would be able to move like that? I don't want Mark to win again, but I see them in the finals.
