Diana/Bex is the romantic/friendship pairing of Biana Amberly Vacker and Dexter Alvin Dizznee.

At first, Dex disliked the entire Vacker family, and only completely came to accept them in Neverseen, when he apologizes. They currently remain close friends, and there seems to be a deep trust between the two.

There is no confirmed interest from Biana or Dex, although Biana and Dex spent a lot of time together when Fitz and Sophie wouldn't include them. They are also very friendly towards each other and are quick to build each other up when the other is feeling down or doubting themselves.

In the deleted scene Biana thinks up ship/platonic names for her and Dex (consisting of Bianex, Dexiana, Vackiznee, and Dizzker.) Sophie is rather confused about Dizzker, but Biana insists that it could work.

It had also been hinted that the feelings between Tam and Biana might be canon, and Dex and Biana also seem to have a strong romantic bond, possibly and probably leading to another love triangle between the three. As of Legacy, Biana and Dex have shown stronger feelings for each other that could possibly hint at a future relationship.
