Maggie Tolliver shows up and gives no real evidence that she's Katarina Rostova, but Lizzie believes her without question, while always riding Red's ass about the truth.
(I'm still of the mind that Red is Katarina.)
If I saw Lizzie coming toward me, I'd run as quickly as possible in the opposite direction. Every time someone comes within 100 feet of her, (s)he winds up dead or hospitalized with terrible bodily damage.
Ressler's animation looked nothing like him.
I appreciate that the crew wanted to finish the final episode, but his likeness was so off. Same with Spader's, somewhat.
Park's was on point, though.
I'll add to the chorus about how adorable Amir's dog is.
Also, I miss Samar.
