Dean-Charles Chapman has played two characters on Game of Thrones. Provide the LAST NAMES of both characters.

On a July 14, 2015 blogpost, George R. R. Martin complimented what GoT actress with the following sentences? Provide the actress’s first name OR the character’s first name, both of which are redacted below: “[Actress’s name] is bright and beautiful, a joy to work with, and she made a great [character’s name]. I've said more than once that it was probably a good thing the character was already dead before I met [actress], or I might never have had the heart to kill her. ((Show [character], thanks to David and Dan and [actress], was actually a much different and more interesting character than Book [character], I blush to admit))

The GoT cast is divided into starring members (names listed during the initial opening sequence) and guest starring members (names listed after the episode). Over the course of the entire series, 3 characters played by guest starring cast members have appeared far more often than most guest stars. These three characters have, in fact, appeared in more episodes than major characters such as Melisandre, Tormund Giantsbane, or Margaery Tyrell (according to imdb). Name TWO of these THREE characters. (provide either first or last name...once you move past the major houses it gets much clearer)

Which starring cast member appeared in the fewest episodes? He appeared in only five episodes, before the death of his character. Name the actor.

Several GoT episodes are named after specific characters, such as “The Red Woman,” “High Sparrow,” or “The Mountain and the Viper.” However, only two episodes refer directly to a character’s given name (rather than a nickname or an indirect reference). Name ONE of these two episodes.

As of August 8, 2017, what is the title of the Game of Thrones episode with the LOWEST imdb rating?
