Limitless continues to get better and better with each passing episode, and "The Assassination of Eddie Morra" kept that momentum as Bradley Cooper made his third appearance on the show. In addition to complicating Brian's life even more, this week's episode introduced a great new character in Piper Baird, who effectively offset Brian's relationship with Eddie. The results offered another strong entry for Brian, as he struggled to do the right thing. Meanwhile, Rebecca's investigation into Eddie's attempted assassination yielded some intriguing moments, including the fact that she's now looking into Eddie's past. Overall, this was an excellent springboard into the back half of the season.
