斯 ('-s,' the universal end-of-foreign-name char). This 4-character pattern transliterates names like Emrys (Welsh, Merlin's true name in BBC's Merlin) or Amulius (Roman king in the Romulus-and-Remus legend). When a fan-subtitled show uses an unusual Western name, this is the kind of phonetic mapping you'll see.
