"Executive Order 13224" is about as packed as an episode can get without going overboard. There are so many things flying around during the episode that the episode could have gotten out of hand under less capable writers. However, the episode is tightly plotted, so the episode more dense than anything else.
Put under personal threat, Alicia hires her own lawyer, Elsbeth Tascioni, Peter's old lawyer played by the very impressive Carrie Preston, who is nothing short of delightful in her attitude and tricks. The case of the week was probably the strongest of the season, with hilarious redacted reenactments (which, I presume, were going on in Caitlin's head), and thorny issues regarding the post-9/11 world.
In another strong plot, Peter tries to go after Lamont Bishop through information on Will provided by Blake. It leads to a confrontation between Peter and Will which almost reached an apex before calming down. It looks like Dana will stay on the show, as the law firm was just using her to lure the person they really wanted.
For the n-th time, Grace had a subplot and it was awful. The writers have been so off-base with the children since the first season that we shouldn't expect more. Grace is back to her idiotic ways, learning about religion through the internet. I understand that teenagers can be dense at times, but it's pathetic how dumb Grace is. She hears that Jesus never said anything about gays but spoke against divorce on numerous occasion, and her thinking changes instantly as she tells her father getting divorced would be bad. As bad as the plot was, it became an afterthought in an otherwise strong episode.
