Probably because her main secret is already out.
With Joe -- he claims thousands of people have been kidnapped over the years. Some of those were likely turned into recruits. This might make the current internment his second go-round in the system -- possibly even for the same faux town square with anyone kidnapped from North America. (As noted earlier, the Sponsors have been preventing escapes for a while.) So if he was brought in/converted on a first trip and kidnapped into a second one, he probably would have been wondering what the hell he did. 'Refresher course' isn't too likely, and he knew he wasn't on the total outs because Tom would communicate with him.
And yet the Sponsors let his image go out to Tori's father. Showing a known operative as an on-site threat? Letting the ambassador know anyone could be at risk? And that presumes the ambassador has any idea who Joe is...
Too few episodes, too many questions.
