Alden and Alina

Alden Vacker and Councillor Alina are not in a romantic relationship. However, Alina likes Alden and was even rumored to have come to Alden and Della's wedding and begged Alden to marry her instead. Alina still has feelings for Alden, much to his dismay. Alina also always sides with Alden.

Similarities:

 * They are both elves
 * They are both in the Nobility (But Alina is only in the Nobility in the later books)

Differences:

 * Alina is a Beguiler, while Alden is a Telepath
 * Alina is on the Council while Alden works as an Emissary
 * Alden does not like Alina while she likes him
 * In book 3, Alden is on Sophie's side while Alina is not
 * Alden is married, and Alina is not
 * Alina likes Alden, while it seems Alden is  'slightly' terrified of her.
