This week on The Flash saw the introduction of none other than Captain Cold!

And there also happened to be an Easter Egg referencing none other than Black Adam!

The beginning of the episode saw a bunch of goons attempting to steal a certain diamond, but were foiled by The Flash.

However, the end of the episode saw Captain Cold steal the diamond from the museum.

So where did the diamond originate?

Kahndaq! The home of Black Adam!

It's a neat little Easter Egg seeing how Dwayne Johnson is playing Black Adam in the Shazam movie, which is due out in 2019.

Hey, maybe Black Adam will come looking for it.

The Flash airs Tuesdays at 8pm ET on the CW.

(Thanks to our own Chris "The DOC" Bushley for the eagle eye!)
