Thanks for the replies. Also, just to clear something up--my current supervisor is not the one who got us behind in the first place. That was my *former* supervisor, who was transferred to another department. My current supervisor is over her department, too.
I tend to believe that the current supervisor knows that the former one had something to do with us getting behind...which is why, I suspect, that she's asking the former supervisor to do calls as well.
But I do agree that the "good employee" vs. "bad employee" thing that's going on is enough to make a lot of people uneasy. Don't get me wrong, I do like to know that my efforts are being noticed and appreciated.

I'm just a little worried about the fall out!
