10 Reasons Why The New Doctor May Actually Be River Song
2. Origins Of A Name
One word which is repetitively used within the 'Fugitive of the Judoon' is "friend". Not only is Captain Jack Harkness referred to as an "old friend" but Whittaker's Doctor was called Martin's "little friend". This word may be small, but it is significant.
While River and the Doctor were consorts, he was always referred to as her "friend" and she, his. This is important when examining Martin'c character. The name "Ruth", when translated into Hebrew, means "friend". Just as River Song and Melody Pond are interchangeable, so is Ruth and "friend". This is a subtle nod to River's character while maintaining her cover under the Chameleon Circuit.
