In Game of Thrones, season 4, ep.8 around 37:50, The Hound says:
[...]and his travelling companion Arya Stark.
He pronounces it like "Aryer Stark". It seems to be a similar concept as an intrusive r, but here the /r/ sound is followed by a consonant.
Could someone share any insight of whether this is a rule, or maybe a question of accent or something else?
