The Walking Dead: Are Glenn And Maggie Married?

During the "Inmates" episode of The Walking Dead, Glenn formed an unlikely alliance with Tara in order to escape the prison. When Tara questioned why Glenn would want her help considering that she was part of The Governor's group, Glenn replied, "I have to find Maggie." When Tara asked who Maggie was, Glenn replied, "She's my wife." Of course, Glenn and Maggie have not been officially married on the show. At least, there's not been a wedding ceremony shown on the show. At the end of Season 3, Glen did propose to Maggie with an engagement ring that he cut off a walker's finger. Maggie said "Yes" to Glenn's proposal, but there was no mention of an official wedding date. Did Glenn and Maggie's wedding occur sometime during the gap between Season 3 and Season 4? Or is Glenn just saying wife because he considers Maggie his wife, even though there's been no official wedding ceremony? In the comics, of course, we already talked about how they did it: In The Walking Dead #37, which is collected in The Walking Dead: The Calm Before, which is a time that was loosely adapted for television, and could have taken place at any time between just before The Governor's first attack on the prison at the end of Season Three and the midseason premiere. In the comics, the wedding (which you can read about in depth here) took place in the prison cafeteria. While we only saw that location once that we can recall–and Hershel might not have wanted to wander back there lest he find bits of himself hanging around–it was a fairly secure location for the wedding, located in an uninfested part of the prison far from prying eyes of people like the Governor who might take such an occasion as an ideal time to spring. It was a family affair, with Billy Greene--Hershel's son, who doesn't appear on the TV series--also in attendance.
