She appeared in 6 episodes out of 110. That's around 5% of the episodes of the show.I wouldnt consider Faith a minor character at all.
In terms of screentime, but in terms of ramifications to the story and moving plot points forward she did more than some regular characters did. In my opinion, Faith is a more important character in the Angelverse than she was/is in the Buffyverse.I know Faith is a big character in the Buffyverse and her presence feels big, but in terms of screentime, she is a minor character on AtS.
Well, if Lilah doesn’t count then I’m going to claim this post as my ownDay 9: Favorite Minor Character
This is always going to be Phantom Dennis for me. It would have been so easy to forget about his existence after the first time, but he hangs around. I especially love the moment from Birthday.
