Amanda Lattimer's unnamed bridesmaids (Bernadette Couture, Angelica Lisk, and Susan Monique Horton) are redeemed villainesses from "Queen for a Day," episode 3.04 of Warehouse 13 (airdate August 1, 2011). They are the bridesmaids for Amanda Lattimer, Pete Lattimer's ex-wife.
In the episode, Amanda--a Major in the Marines--was set to marry her fiancee and fellow marine, Michael Martin, and Amanda was shown at Warehouse 13 informing Pete about her upcoming nuptials. While there, Amanda picked up one of the artifacts; a golden beehive belonging to Queen Hatshepsut. The beehive contained a live metal bee, which accidentally fell in Amanda's purse and stung her later in the episode. With the stinger in her finger, Amanda became an inadvertent "queen" and contained pheromones that turned those around her into her "servants" with a single touch.
Amanda's bridesmaids were the first to fall under the spell when they noticed her bruised finger, and became doting on her when they touched her, as did the groomsmen. Later on, Amanda saw Michael's parents (her future in-laws) coming and wanted to avoid them, leading to Amanda telling her bridesmaids and the groomsmen to "take care of them." The mesmerized sextet took Amanda's words seriously and literally tied up the Martins before locking them up. Pete and Myka Bering arrived at the wedding at the Poconos and informed Amanda that there was a problem, without revealing the truth. A search in Amanda's purse ended with the bee recovered and placed in the negation bag, with all three believing that their problems were over.
However, the stinger was still in Amanda's finger, and also, the villainous bridesmaids and groomsmen over heard Amanda saying that no one would get in or out of the wedding, as well as Michael jokingly saying to Amanda that he would "own her." This led to the group preventing Pete and Myka from leaving, with the duo seeing that their mission was incomplete. A call from Artie Nielsen revealed that Hatshepsut's servants were so obsessed with her that they resorted to mummifying her husband alive, as he would have enough power to take the throne. The evil bridesmaids and the groomsmen were attempting to do the same to Michael, ignoring Amanda's attempted "command" to stand down while doing so. A fight ensued, with Amanda, Pete, and Myka battling against the drones, which saw (among other things) Amanda knock out one of the bridesmaids with a microwave gift, allowing Pete to rescue Michael. Meanwhile, Myka took out the bee and used it to pull the stinger out of Amanda's body before placing the entire bee back into the negation bag. As a result, the bridesmaids and groomsmen were back to normal, and they took their place at the wedding; bruised, but redeemed.
