Original Commentary
Not a new background, sort of. The apartment's mail center was made just for each panel, although it would have been smart to have just made one background, if only for the third panel, since the other panels would have needed custom made backgrounds as it was. Ah well, live and learn, right?

So what is in the envelope...? Only time will tell... sorry. ._. -Isabel

Modern Commentary
Seriously, replace the first panel of this comic with the first panel of the last comic and there you go. - Terrence
