Pyfrom, who portrays Bree's (Marcia Cross) son Andrew, will reemerge in Episode 18 of the final season with a big announcement. While details are scarce as to what he'll be revealing to dear old mom, let's just say things have certainly changed since he's been away.

We last saw Andrew in Season 7 as he battled with alcoholism before finally admitting to Carlos (Ricardo Chavira) that he had mowed down his mother with a car.

Desperate Housewives airs Sundays at 9/8c on ABC.
