Poor Shadowhunters fans. Despite a massive social media campaign to keep the Freeform show from being banished to the land of wind and ghosts, the series is currently slated to air its final 10 episodes in 2019.

Fans hoping to snag a piece of their precious ended up with a little more than they bargained for when signing up for a prop auction hosted by 403 Auction. While most of the props up for grabs were of the generic, unspoilery flavor, some of the swag inadvertently revealed major plot points for the upcoming final episodes.

In particular, a detailed letter from Clary (Katherine McNamara) to Jace (Dominic Sherwood) outraged spoiler-conscious fans and sent the hoards to Twitter to make their concerns known. Co-showrunner, Todd Slavkin. responded to a concerned fan with, "We are aware of auction but had no idea about spoilers. That sucks on so many different levels."

Since their discovery, the spoilery items have been removed from the auction, which continued through September 6, if you want to get your hands on some bows, swords, or a SWEET "panDEMONium" bar sign.
