The renowned Prime Video’s The Boys season four threw a major curveball in episode seven with the introduction of a shape-shifting Supe and a cliffhanger that left fans questioning who’s who.In an interview with Screenrant, the series director, Catriona McKenzie (Satellite Boy), explained the subtle signs that viewers can use to deduce who the imposter is.

McKenzie stated, “Erin’s so amazing. We talked about her physicality, we talked about her eyes, and we talked about a stillness because the Shifter doesn’t have the same kind of emotional, intuitive, emotional intelligence that Annie does. And we’ve seen that in the episode; there was just a stillness that she brought to her performance where she’s just a bit more robotic. It was fun working that up with her.”

She continued, “And she’s a natural. Basically, everything’s the opposite of what she’s developed, and she just moved away from her instincts. I think, as a director, it’s more and more about the subtleties of working with actors and working on characters that I find brings such pleasure. The minutia of performative detail is where I think is the goal is, and I love that moment when she gets out of bed and walks past Huey. She walks over to the safe, and you just know we’re in for a ride.”

According to Screenrant, this new supe will shake up the current mission of Butcher, played by Karl Urban (Star Trek), Homelander and Vought by stopping the assassination of President Singer while also trying to take down Homelander. This twist adds a layer of intrigue to the remaining episodes within the fourth season. The previous six episodes are available to stream on Prime Video, and the seventh will be released on July 11. If the story of this season goes well, it could set up for the approaching fifth season.
