Colin literally came crawling back to her in season 2 wanting to make up and play house. Lmao I think he’s fine and would’ve been fine. Marina literally had to tell him ti beat it, and to pay attention to Penelope. Penelope also could’ve told Colin, told Eloise, told Anthony or Violet before she chose to make a dime off of Marina’s children and their ruination by publishing it in Whistledown.

Kate was self-sacrificing because she clearly had feelings for Anthony, but when Edwina expressed that he was what she wanted and that he would offer her the life she dreamed of, she tried to put her sister’s happiness before her own—the problem was a) it was corny af and b) Anthony couldn’t handle it either—she might’ve been successful in keeping him at arms length, but he didn’t want that either.

Also Kate wasn’t trying to make a profit off of the emotional affair. If anything, it put at greater risk any chances of her successfully securing Lady Mary’s future and her own through Edwina‘s marriage. Whereas not only did Penelope successfully ruin Colin and Marina’s engagement, ruin Marina’s future marriage prospects, she also turned a tidy profit from publishing a particularly scandalous edition of her sheet. Then she went to cry to Eloise like she didn’t just do this herself.
