[Mid-credits scene: At an underground HYDRA lab, Baron Wolfgang von Strucker is talking with a HYDRA scientist]
It's over. Fury has released everything to the public.
Everything he knows about.
Herr Strucker, if they get word of our work here, if they find out we serve HYDRA...
HYDRA, SHIELD, two sides of a coin that's no longer currency. [They walk over to the corner of the lab where Loki's scepter is being kept] What we have is worth more than any of them ever knew. We've only scratched the surface and already... there are other facilities doing HYDRA's good work around the world. We'll feed them to Captain America and his colorful friends. Keep them off our scent.
What about the volunteers?
The dead will be buried so deep their own ghosts won't be able to find them.
And the survivors?
The twins. [referring to Pietro and Wanda Maximoff, aka Quicksilver and Scarlet Witch, being kept in glass cells each exhibiting their powers, Pietro having superhuman speed and Wanda having telekinetic powers] Sooner or later they will meet the twins. It's not a world of spies anymore, not even a world of heroes. This is the age of miracles, doctor. There's nothing more horrifying than a miracle.
[Wanda is telekinetically holding a cinder block before destroying it.]
