the actress in question is Amy Price-Francis
. Be careful with that link, because towards the bottom is an indication as to how long she will be on the show.
If I'm not mistaken, Amy Price-Francis' name was actually in the opening credits of this episode. I deleted the episode, but it should be pretty easy to verify.
As for the episode itself, it was pretty unremarkable. Still not buying the Tony twist.
And dammit, I missed Agent Freckles' PSA and only saw the one with Tony at the end.
