From the documentary, "Figwit Lives"
There is no shot in the movie of the Dwarves arriving in Rivendell that show anyone but Gloin and Gimli.
Gloin is shown arriving at Rivendell but is not at the Council.
This Dwarf is not shown arriving at Rivendell in the movie. I don't believe it is one of the Dwarves at the Council.
This Dwarf is not shown in the movie.
