I'd like to hear more from Vader about what he meant when he said "If anyone wants to confirm this", but he pretty clearly messed up, the only question is whether this was a townie making the mistake of not checking his PM or scum finding out too late that two people had confirmed his fake claim was bogus. I think That2 and JoeBob are basically confirmed town since each of them independently claimed to use a role that contradicted Vader's claimed actions.
That leaves Owen, Pie, and me. If we weren't at MYLO, I'd be willing to roll the dice and role confirm myself while simultaneously taking one of them out, but we don't have that luxury at this point. It seems like a pretty weak town setup, given that we apparently have a Vanilla and a Hated with only one protective role (Earth's BG) and one investigative role (That2's Watcher) and only JoeBob's Conditional Vig adding a bit of potential swing to the mix. If I had to pick between Owen and Pie, I'd say that Owen claiming the Hated at this point when town cannot afford to policy lynch him stands out more, especially since we don't know whether his role persists into MYLO/LYLO.
