Now Harry, Hermione, and Ron were searching out the Horcruxes. No one had yet to figure out that Hermione and Harry were dark, Draco was the only one who came close, he had recognized Harry’s wand in that moment, but a perfectly placed obliviate later and it was all hunky dory. When they found a Horcrux Hermione would transfigure a duplicate and Harry would cast an illusion spell he created to represent the reaction one has when destroyed, all the real ones were hidden away in Harry's trunk. They both knew what he was, knew he was also a part of the matching set and that's why Harry dealt with handling them, they only purred in recognition of another soul shard. Ron was none the wiser that he was practically handing the war over to the dark.
