'The Americans' Season 3 Spoilers: Twitter Reacts To Keri Russell, Lois Smith's Adele Stackhouse Shocker! [WATCH]

Season 3 of The Americans had the most shocking and heart-breaking conclusion last night on FX. Twitter had lots to say about Elizabeth Jennings (Keri Russell), at her cruelest with the elderly Betty Turner (Lois Smith, who memorably played Adele "Gran" Stackhouse on True Blood).

In our previous recap, after completing Gabriel (Frank Langella)'s orders, Elizabeth asked her handler for a favor, to bring back Philip's son, a solider, from the war. In order to get a lighter sentence, Nina (Annet Mahendru) has to gain the trust of scientist Anton Baklanov. When Martha (Alison Wright) confronted her husband about the interrogations going on at the FBI's office, Philip told her the truth; he's in love with her. The two were uncomfortable sitting in the same bed together.

In our recent recap, Martha gave Philip inside scoop about what was going on inside FBI headquarters, as if she were playing along. With Martha's info, Philip and Elizabeth broke into the storage room, attempting to put a bug in the mail robot. Unfortunately, Betty was at the wrong place, at the wrong time to be working late.

During the night, Betty talked about her marriage and children, even showed their pictures, as Elizabeth forced the elderly woman to overdose on her pills. Betty asked, "Will my death make the world a better place?" After Elizabeth said yes, Betty responded with her last words, "That's what evil people say..." before dying.

Check out what Twitter had to say about Betty Turner's last hours with Elizabeth:
