The season four finale of The Wire marks the return of Paul Ben-Victor’s character Spiros “Vondas” Vondopoulos. I have no information at this time as to whether this is a one-episode return or if Paul’s character is back on a more recurring basis.
The name of the episode is Final Grades. I’m late reporting this, but there are a couple of airings left of this episode: one on February 6, 2007 at 11:00 p.m. on HBO East, and again on February 7, 2007 at 2:00 a.m. on HBO West. As usual, check your local listings. If you have HBO On Demand, you can also catch the episode during its run from February 12, 2007 to March 4, 2007.
