There's one, huge, really obvious Easter egg in Supergirl this week, but that didn't stop them from having a little bit of fun with the rest of what was going on in the show.
Aside from the famed Alan Moore story at the center of the plot, we saw some familiar names and faces from Krypton and beyond in tonight's installment of the CBS superhero series.
So...what did we see? What did we miss?
Read on, and comment below.
FOR THE MAN WHO HAS EVERYTHING
The classic Superman story "For the Man Who Has Everything," published in Superman Annual #11 from the Watchmen creative team of Alan Moore and Dave Gibbons, was the inspiration for tonight's episode of Supergirl.
"Episode 13 is based on one of my favourite Superman stories, 'For the Man Who Has Everything,'" said Supergirl executive producer Andrew Kreisberg at the Television Critics Association recently. "It's called 'For the Girl Who Has Everything,' and she wakes up on Krypton in this fantasy that nothing ever happened. I've literally been pitching this from this first episode!"
The story, which sees Superman put to sleep with an alien plant that makes him imagine his fondest desires have been met, was previously adapted as the second episode of Justice League Unlimited. In the comics, Batman, Robin and Wonder Woman play key roles, and the villain is Mongul.prevnext
Kelex gets around.
If anyone had any doubts that this wasn't the same world as Man of Steel, the appearance of Kelex -- which echoes the John Byrne design for service robot from the '80s in the comics -- should put them to rest. In the most recent Superman movie, Kelex was matte black and a kind of liquid metal.
A version of Kelex, designed by the pre-Flashpoint Superman to watch over his new Fortress of Solitude-like "workshop," debuted in a recent issue of Superman: Lois and Clark.prevnext
Argo is a major city on Krypton, and the birthplace of Supergirl, in the comics.
It's not clear whether the scenes that take place on Krypton in Supergirl take place there, or on Kandor, the capital city, which was later bottled by Brainiac and kept for years in Superman's Fortress of Solitude.
Apparently, though, there's an "Argo Fever" which would have had incapacitating and hallucinatory effects on Kara...or at least if not, her brain made that up so that the situation she was in would make some kind of sense.prevnext
The "Myriad" plan is apparently tied to the forthcoming introducion of Brainiac-8 (or at least we're guessing), but that name has been seen before in Superman comics.
Myriad was the name of one of the Bloodlines heroes -- a woman murdered by Lex Luthor who was revived when an alien tried to eat her body...but when she came back, her brain was essentially blank and could be imprinted over by the personalities of people she touched.prevnext
INTERGALACTIC PARAMILITARY FORCE
In most versions of his origin, J'Onn J'Onzz was a cop before the fall of Martian society.
We're not sure if it's this, the DEO or something else he meant when he said he's a member of an intergalactic paramilitary force, but it seemed worth pointing out, at least.prevnext
Referring to Earth as "primitive" might just seem like a defense mechanism on behalf of the Kryptonians simulated by the Black Mercy when Supergirl starts to believe that she had been sent there...but there could be more to it than that.
Lara believes Earth to be primitive in The Man of Steel #1, as seen above, and doesn't want to send Kal-El there.prevnext
Max Lord asks for a case of Dr. Pepper for helping stop the Kryptonians' master plan...
...which could just be a cute throwaway line if last week, Batman V Superman: Dawn of Justice hadn't just announced a new promotional digital comic that fans can read by scanning bottles of Dr. Pepper.prevnext
