Yeah everything leads back to Russia. It was a good episode too though so what was left in was good
ETA: Now on to the final episode which also has deleted scenes...
Spoiler:
Nell goes to talk to Kensi about taking over for Hetty. Then Kensi wonders where Deeks is.
Killbride talks with Kensi & Deeks in the gun room (I forget the proper term for it) & tells them that he hopes that the Russians attack them with lethal force (so that they could respond in the same way) -
watch the scene here
Roundtree & Fatima talk, he tries to make small talk with her & get her to talk to him about whatever is going on with her. Says he's there if she ever wants to talk
