4x09 Broken Promises
First Aired: Jan. 10, 2017 on ABC
Summary: On the heels of their encounter with Ghost Rider, their strangest phenomenon yet, the Agents of S.H.I.E.L.D. suddenly find themselves up against a myriad of new and ongoing threats: The anti-Inhuman Watchdogs are gaining political influence with Senator Nadeer, and uniting behind a …
Leo Fitz: Yeah, well, normally we can, only Aida's somehow managed to take control of her entire operating system.
Holden Radcliffe: Which unfortunately includes her tracking program.
Phil Coulson: Meaning Aida can read her GPS history?
Phil Coulson: That's not good. That's bad.
Jeffrey Mace: I don't want to chase conspiracy theories.
Daisy 'Skye' Johnson: It's not a theory if I can prove it.
Phil Coulson: Yeah. Question is why.
Alphonso 'Mack' Mackenzie: If we catch her, maybe I'm sure we'll get some crazy-ass Roy Batty explanation.
Melinda May: Maybe Nathanson saw something he wasn't supposed to see.
Phil Coulson: Guess we won't know till we find Aida.
Alphonso 'Mack' Mackenzie: First, maybe lock up the guy who created this mess.
Holden Radcliffe: Don't - Don't be so quick to judge. Aida's programming was perfect. This is - is clearly the Darkhold's fault.
Phil Coulson: You're saying reading the Darkhold may have corrupted Aida's programming? Is that even possible.
Leo Fitz: Technically, no, but we are dealing with a book that can read people's minds and also reveal the hidden secrets of the universe, so...
Melinda May: I never should have let Aida near that thing.
Holden Radcliffe: Don't be so hard on yourself, Agent May. I, for one, am glad that Aida read that book. Otherwise, both of you would not be standing her alive at this very moment.
Alphonso 'Mack' Mackenzie: Well, book or no book, you're still a big, dumb idiot for building that think in the first place.
- SPOILER: Aida still has the real May locked up and drugged, while the fake May is at SHIELD
- Simmons refers to the Director's assistant as" the Director's little Smithers" which is a reference to the character from the TV show "The Simpsons" where Smithers is Mr. Burns shady assistant.
- When Mack approaches Fitz and asks how Radcliffe is holding up, Fitz's responds "He's taking it pretty hard, actually. Aida was his life's work. She was kind of like a child". Mack comments in return; "Small wonder...". This is a reference to the 1985 TV series Small Wonder, which was based on the premise of a female child robot named VICI, who was created to be a domestic aide.
- Mack references numerous robot and AI-related sci-fi/horror movies and television shows (mainly from the 1980s) through the course of the episode. Those mentioned include Maximum Overdrive, The Lawnmower Man, The Terminator, Short Circuit ("Johnny 5"), Blade Runner ("Roy Batty"), Small Wonder, and Chopping Mall.
