The extent of Digby's knowledge of the plot is unknown, but in the opinion of author Alan Haynes, Digby was shocked by what he heard, and asked what would become of some of their Catholic friends. Catesby replied "Assure your selfe that such of the nobilitie as are worth the saving shalbe preserved and yet knowe not of the matter." None of their friends would be caught in the explosion. He asked if Catesby had spoken of the matter with Garnet, or any other Jesuits; although Catesby was in no doubt that the Jesuits disapproved of any such action, he lied and said that he would not act without their approbation. Catesby then named the other conspirators, and promised Digby that as soon as they reached Gayhurst he would demonstrate that their religion allowed such acts of regicide, thus dissuading the young lord from confessing to Garnet and discovering the Jesuit's opinion of the matter. Catesby told him to rent Coughton Court from the head of the Throckmorton family, so that he would "the better to be able to do good to the cause Princess Elizabeth". From there, he was to organise a hunting party (in reality a group of armed men on horseback) and be ready for some kind of military manoeuvre. Digby also provided monetary assistance; he promised £1,500 after fellow plotter Thomas Percy failed to pay the rent due for several properties in Westminster.
