Biana and Dex

Diana/Bex is the romantic/friendship pairing of Biana Vacker and Dexter Dizznee. At first, Dex despises the entire Vacker family, and only really comes to accept them in book 4, when he apologizes. Later, both Biana and Dex do not show any feelings toward each other than friendship, but some fans of KOTLC like to think otherwise.

Both have shown stronger romantic feelings for other characters, Biana for Keefe and Dex for Sophie, until later books when moments between the pair become less frequent. In Book 5, Lodestar, there were many moments that hinted at a possible relationship between the two, but up until that point there seemed that neither held romantic feelings for the other. It had also been hinted of that feelings between Tam Song and Biana might be canon, possibly having another love triangle for the three.
