I was hoping since season 1 that they would have Richard on, he'd make a great energy vampire.

The cast was very kind, though my department isn't on set much so it would just be brief hallway or parking lot interactions. Matt Barry was always a gentleman, holding doors while we dragged scenery through. And Harvey always said hi as he passed even though he knew none of us. I can speak to all of them, but it's a repeat of "had minor contact, they were lovely people".
