No. The Void gets lonely, and it looks for a partner. You can't really kill someone Void-touched in the Void without the Twin-Bladed Knife, which you didn't have or even know about at the time, so there was no dispatching me then. There was no stopping the Void from latching onto Dorsey, either; I was as surprised as you were to find out he was really there and not another shadow.
