Last week's episode of "Agents Of SHIELD" Season 4 showed Director Mace being taken as prisoner by the Superior aka Anton Ivanov. Fitz and Simmons track Ivanov's base, and then a big revelation happened. Major spoilers ahead.

According to Entertainment Weekly, AIDA was partially designed by Fitz, and so Fitz blames himself for creating the tech that is imprisoning May. It turns out that Ivanov was just a manufactured bad guy to distract SHIELD. He is just AIDA's pawn to lure SHIELD into her web, and AIDA was able to replace Coulson, Mace, Daisy, and Mack with LMDs.

"Agents Of SHIELD" Season 4 episode 14 has been a roller coaster of revolving villains - from AIDA then Radcliffe, then Nadeer, then Ivanov. Fitz needs to think about the potential implications of the things he creates. How will they be able to handle their friends' LMD version?

This plot twist was last week's main event. Also, AIDA is turning into a huge villain. The ending was quite a cliffhanger, and so "Agents Of SHIELD" Season 4 episode 15 is going to be very exciting. This week's episode may show how Fitz and Simmons will face off against the bots that replaced their friends.

The LMD arc is nearing its end in general, and so the story could hit a peak this week. What's chaotic is that nobody knows who to trust and there's going to be opportunities for each member of the crew. Everyone could be on high alert.

ComicBook said that synopsis for episode 15 titled "Self Control" is already out. SHIELD is overrun by LMDs; there is no one to trust. The official synopsis says: "Suspicion turns to paranoia when the team doesn't know who can be trusted as more LMDs infiltrate SHIELD." The episode is written by and directed by Jed Whedon.
