We really get to see how much ass The Cavalry can kick in one of the most intense martial arts fight scenes that I've ever seen on a TV show, with the finishing move of the fight reminiscent of a Tony Jaa film (and if that name means nothing you, I beg you to watch Ong Bak, or at least a few YouTube clips). The entire thing is basically just a reminder that Agent May is a badass of similar calibre to Black Widow, and it absolutely works in that regard. In fact, the entire episode is fairly May-centric, with the majority of the running time being used to remind everyone of what an excellent Agent she is.
Unfortunately, this results in less screen time being given to the newer characters, and the episode ends up feeling a little more season one than season two. The self contained nature of the episode, along with the increased focus on
Still, we get some great moments from Agent May, and Ming Na Wen really gets her time to shine. We get a wide range of emotions and actions that Agent May goes through in this episode, and there isn't even a single moment that the character feels unbelievable or poorly acted, partly in thanks to the quality of the writing and partly thanks to the consistent performance that Ming Na Wen gives. Even the poorer first half of the episode has some great moments, including an undercover Agent May confusing and scaring everyone back at base simply by laughing, an action that no one knew May was capable of.
To say that "I Will Face My Enemy" is saved by the fight scene would be doing a disservice to the rest of the episode, but it's certainly the most memorable aspect of an otherwise fairly standard story. It suffers early on, but picks up speed in the final half to deliver an episode that is, on balance, not quite as good as the previous three, but still thoroughly entertaining, and if this ends up being the weakest episode of season two, then we are in for a real treat.
