Purity bond

A Purity bond is a pledge that Bree was required to keep as part of her religion. The exact nature of the purity bond has never been revealed.

In the YouTube comments to the video Boy Problems... Bree first mentions that one of the reasons her parents would never allow her to date Daniel is their belief in purity bonds. Fans at the time, who would comb over the comments to every video, googled the phrase "purity bonds" and discovered that it did not appear to be used in any real religion.

Most people believed the purity bond to be something similar to a virginity pledge, where a young man or woman pledges not to have sex before marriage. Most signs pointed to Bree's religion having a connection to Aleister Crowley, but Crowley was known to be quite open about his sexuality.

In the video My Difficult Decision Bree says that her parents told her that she had violated her purity bond by sneaking out to meet Daniel and by kissing him.

The purity bond has not been mentioned since, and it is unclear if Bree still feels bound by it, whatever it was. She probably does not, considering her rebellion and disillusionment with the Order.
