Supernatural, obviously, revolves around Dean and Sam, but we've seen many minor characters like Bobby, Helen, Jo and Castiel (even though it breaks my heart to call him a minor character.. according to screen space he is, but in my mind he's up there with Dean and Sam). So my questions is, who's your favorite minor character? Now most likely the person playing that role would be your favorite guest star, but if it's someone different, do let us know!
Some of my favorite minor characters are, of course, Bobby, Helen, and Jo. If we consider Castiel to be a minor character (which I so don't) then undoubtedly he's my favorite! Bobby is also one of my favorite characters. I literally cried when he died. Also when Helen and Jo died. That was a very emotional moment.
Other than them, I also really enjoyed Trickster/Gabriel. The episodes he was in were just funny overall, and even though I started out not liking him, he grew on me.
And I hate to say it, but I liked Lucifer as well, especially when Sam hallucinates about him. He was kinda hilarious! Mark Pellegrino did an absolutely brilliant job in that role.
