Clyde Easter

Clyde Easter was a former partner of Emily Prentiss during her Interpol days.

Background
Clyde was a British spy who was team leader of an elite team comprising of Emil Prentiss, Sean McAllister, Tsia Mosley and Jeremy Wolff. The team's job was to track high-profile terrorists, profile them and then go undercover to bring them down. Usually, the country in whic they were operating used their own secrurity services to bring them down when enough intelligence had been gathered.

Seven years before Season Six, Clyde and his team were charged with tracking down and bringing down a former IRA captain named Ian Doyle. Prentiss went undercover as Doyle's lover and he was later arrested. Clyde arranged for Doyle's transport to Camp 22, a North Korean off-the-books prison where Doyle was interrogated for seven years.

After Doyle escaped from prison, Clyde realized that someone had betrayed the team to him. He soon learnt it was Jeremy and he also begun to suspect Tsia, Jeremy's girlfriend, of being in on it.
