You can blame those darn fish oil pills for the sudden influx of Inhumans. Now that the supplements are hitting the shelves, any one who wants to lower their triglycerides may accidentally tap into their latent Inhuman DNA. After all, no body knows just how many descendants there really are.

Aside from the casting announcement, Marvel has kept a fairly tight lid on any Lash spoilers. Elizabeth Henstridge (Simmons), however, is particularly excited for viewers to meet the newest member of the MCU, in part thanks to the makeup team that has crafted his unique look.

"He's going to shake things up," Henstridge told Zap2It. "It's going to be a huge spectacle. We're so honored to be able to have him in the show. It's just huge. I can't even explain how crazy it's going to get."
