10 MCU Movie Teases That Went Absolutely Nowhere

1. The Other Widows

What Happened

When Scarlet Witch showed Black Widow the haunting vision of her past, we got to see flashes of her early years in the Red Room, where she was programmed to become Black Widow through some nightmarish processes.

Intriguingly, the vision reveals at least 13 young subjects who have been put through the same "training" as Natasha.

What it Teased

That there are other Black Widows (just as there have been in the comics) - or at the very least other trained super assassins with different codenames. And presumably, the "mentors" we see at the Red Room might have something to say about Natasha running away to join the good guys, with a little help from their team of assassins.

But Then...

So far, nobody has even come after Natasha, despite her turning her back on the Widow programme (and presumably running away). And there have been no appearances by any of the other Widows, which really makes you wonder where they all went.
