Fans of the TV series Fallout think they've discovered a huge 'easter egg' for the second season of the Amazon Prime series.

Fallout was released on April 10th to rave reviews. A second season of the series is all but confirmed. Fans believe they have discovered details about a revelation.

In episode six of season one of Fallout, Cooper Howard encourages viewers to call Vault-Tec to secure a spot in one of the shelters by dialing 213-25-2858. He gives an important hint about when we can expect news.

After dialing the number, fans will hear a person who sounds like they are being tortured, occasionally screaming and letting out heart-wrenching cries until the call is disconnected. If you want to avoid that, you can text the number instead.
