1st comment awesome!
But seriously I adored this season the best because all of the stuff that happened:

There was Jai's death of course, which was really sad because I truly don't think we ever got to know him.

Danielle leaving Annie to move to California, I hope she comes back in Season 4!

Annie & Auggie's reassignments then being sent back to the D.P.D , Annie & her whole mission with Simon Fischer, then he gets killed and she gets shot by & framed by Lena, then subsequently shooting HER , then being imprisoned in Russia!

Also this season was a huge one for Auggie he not only proposed to Parker but shortly after that they got captured by pirates! and he was forced to come clean about his CIA status, which led to their break up which led to him going off of the rails for a tiny bit! I LOVED how he enlisted Eyal's help in saving Annie in Russia that was the coolest moment in the series so far! I also liked the positive changes Auggie had, I loved how he went back to Iraq and I think he finally got the closure he desperately needed!

And of course the main reason why I loved this Season the best was Annie/Auggie FINALLY kissed, I am crazy psyched to see how their relationship deepens come Season 4

I still don't get what Henry Wilcox's end game is but after he gave Annie that file I am SUPER excited for July to find out what it's contents are!

Covert Affairs is getting better and better every season ! Season 4 is already amazing!
