I mean exactly what I said, that they can handle the truth. Desert has nothing to do with it. In either event, let's look at some scenarios, shall we?
Spoilered so the discussion can be ignored. And why not, let's include a trigger warning as well.
But to bring this back to Gargoyle's situation: If he wants to be someone people tell the truth to about himself, he has to be someone that can handle that. It looks like he is trying to be that sort of person, and it sucks that people are still uncertain about the type of person he wants to be. Of course, if he continues on his path, they will begin to trust him. It's a process, sometimes long and tedious, but people (the worthwhile ones anyway) can see that and adjust their behavior accordingly.
