Prince Harry and Meghan Markle might be two of the most scrutinized people in the world right now, but in 2016, their relationship was a secret from everyone except a select few people. However, an apocalypse-themed Halloween party that year marked a turning point for the couple, who headed out for one last night of freedom with Harry's cousin Princess Eugenie and her now-husband, Jack Brooksbank.
The Duke and Duchess of Sussex recalled what happened that night in both their Netflix documentary series Harry & Meghan and the Duke of Sussex's memoir, Spare, with the Sussexes sharing that they knew their time was running out when it came to keeping their relationship under the radar.
