Annie is canon through the first three seasons of Covert Affairs, though after two and a half years of RP, her personal canon is a little different.
Her current storyline has her recovering from a year and a half long relationship with Clayton Webb, whom she still loves. He is Deputy Director of Counterintelligence with the CIA. Their friendship started before the first season of Covert Affairs, but to stay canon compliant, they broke up shortly before the second season began. Now, they have an on/off relationship that consists mostly of a sexual relationship, though they're still crazy in love.
