The Walking Dead: Former cast members return to celebrate episode 100 

cast members and executive producers took the stage at the Greek Theatre in Los Angeles for a two-hour live

, which also happened to be the 100th episode of the AMC zombie drama. But they weren’t the only ones on the stage.

Host Chris Hardwick also brought out several former cast members who characters were killed off along the way. Sonequa Martin-Green (who played Sasha), Emily Kinney (Beth), Scott Wilson (Hershel), Iron-E Singleton (T-Dog), and Michael Rooker (Merle) were surprise guests at the soiree, while Steven Yeun (Glenn) and Sarah Wayne Callies (Lori) sent in video messages.

We have this exclusive photo of the whole gang together on stage from the event, along with some nifty episode 100 balloons. Enjoy the group shot and then make sure to check out our episode Q&As with
