5 new insights about The Walking Dead learned at PaleyFest LA

You would think a show that's been around for what seems like forever, that everyone would know each other. However, with characters spread among four communities, it has led to some cast members not meeting until now.

Scott Wilson was incredible as Hershel. He passed away in October. He was last seen in season 9 episode 5 for a short cameo appearance. The cast said he is still missed and will always be TWD family.

Several cast members of TWD are learning ASL in support of fellow cast member Lauren Ridloff, who is completely deaf. There have been moments when cast members accidentally messed up signs.
