I find it interesting that both Quentin and Barnabas seem to have been hired as total villians, only to quickly become favorites and have their characters softened and fleshed-out...
How long before Quentin talks?
And out of curiousity: I remember Quentin & Beth, Daphne & Gerard... all being silent ghosts for a long time before getting their first lines of dialog. Were there others that started as a non-verbal presence?
Which regular has the honor of being mute the longest--before the powers-that-be gave them their first lines of actual dialog?
