Jackson Gibbs was targeted by Paloma Reynosa. However, to her surprise, Jackson was ready for her and stood his ground. He aimed to kill her with his Winchester, but missed. The shot alerted the town and while Reynosa drew her sidearm, Jackson was certain that even if she shot him, his next shot wouldn't miss. She left, ordered her men to open fire, and then checked the wreckage of the store to find Jackson had gotten clear. He spent the next several months in protective custody at Gibbs's house.
