TVLine.com — No news is good news in French Court, which makes TVLine’s exclusive shot from Thursday’s Reign (The CW, 9/8c) all the more ominous.

Pictured above, Mary has a little chat with her uncle, the Duke of Guise (guest-star Gil Darnell), about a letter she sent to Catherine of England — and judging by the looks on their faces, methinks they don’t quite see eye to eye on the written word.

And this letter scuffle is only part of Mary’s headache this week; the penultimate episode of Season 1 will also find her teaming up with Catherine (yes, you read that right) to “deal with the increasingly manic King Henry.”

Should be a lot of fun, all around!
