All the problems I had with the pilot remained in "Walter's Walk"--everything outside of Annie and Auggie isn't fully functional yet, unable to stand on its own. Joan and Arthur remain, essentially, as foils for Annie, showing the personal lives of a CIA couple, without fully fleshing them out as real people first. In place of Conrad who hardly did anything in the pilot, Jai Wilcox (Sendhil Ramamurthy), who is ordered by Arthur to get "close" to Annie, so he can info from the elusive Ben Mercer. Why is Ben important? We still don't know, but considering this is a USA show, I'm guessing it's not very complicated.
On the positive side, Annie and Auggie remain as awesome as ever and their training session was positively delectable. Faced with Danielle asking her if she'd take care of her daughter if something happened to her and her husband, Annie faces a "life issue," whether see will be able to balance her spy life and family life. Needless to say, Annie isn't a horrible person who would let her niece out into the cold and signs the paper; however, the warning signs are out there and will forever loom over her.
There wasn't much to see with the plot, a pretty basic spy story. A young genius discovers some numbers being broadcasted, indicating IRA involvement. Annie meets an MI6 agent who turns out to be a double agent and saves the day.
While the rest of the show hasn't convinced me yet, Piper Perabo is a pure gem and is just as good in the second episode as she was in the first. For that reason, I don't think I could stop watching the show, even if the rest of it continues to lag behind.
Score: 8.4/10
