There's pluses and minuses to having Tanith commentating, as long as you know she is Charlie's girlfriend.
You get some details about the skating of dancers in the Detroit skating community that you just would otherwise never hear. And she is actually an ice dancer who competed in both 6.0 and COP and discuss both knowledgeably.
Other media outlets of course have color commentators who have a conflict of interest sometimes! Does Tarasova not comment on skaters whom she has worked with (or skaters who compete with those she has worked with). How about Sandra Bezic and choreography7 How about Scott Hamilton and skaters that he has hired?
Sometimes the strangest dynamics apply: Nicky Slater's mother coached C&L's ex coach. As long as C&L were with the coach, Nicky was a ridiculously huge fan (he disclosed this on air one time).
