The proposal occurred on September 23rd, 2017. It was done during a Gender Reveal party for one Sarah Cole.
The actual proposal was done by Jason asking Alice to make him a Mohito. While she went into the kitchen to do so, Sarah placed the ring on Alice's lizard's (Azzie) tail. After doing so, she went and asked Alice what the growth on Azzie's tail was. Alice came running to check.
Alice, after the initial shock, then responded with her own proposal to Jason.
Both parties fully agreed to the commitment. With this done, both Satanists had accepted a new god into their lives, each other.
