Of all the people to trust with the Darkhold on Agents of S.H.I.E.L.D., I would not have gone with the guy who had a vision/murder board for Phil Coulson, but I'm sure Aida has her reasons — even though this totally seems like a super-villain origin story. What happened to The Superior on Agents Of S.H.I.E.L.D.? Dr. Radcliffe's LMD made some modifications to her new right hand man.
Namely, she put his human head in a glass case so that he could remotely control his new robotic body. That's one of the most outrageous and creepy things this show has ever done. Doing so saved his life, albeit against his will. Daisy quaked him under a pile of rubble in the previous episode, and Aida restored his health as he protested her methods.
Also, Aida killed Dr. Radcliffe. That kind of got lost in the shuffle of such an explosive episode. He's not quite gone from the show yet, because he still exists in the virtual reality framework, but Aida did quickly kill his mortal body.
In a way, Anton deserves what happened to him. He hated Inhumans and LMDs so much, and now he has become what he would consider to be a monster. On the other hand, that is a lot of power to hand over to such an unstable person, even before that evil magic book got involved. I don't understand why Aida chose the Superior for this particular experiment. I don't understand a lot of her plan, actually. Besides the cool Battlestar Galactica reference, what's up with the army of Daisys? In her final scene with Anton, Aida expressed a desire to have desires — to become real and feel human emotion. The LMD arc is not quite as over as it seems. There are still a lot of questions to be answered when S.H.I.E.L.D. returns in April.
