Question: Other than "stage directions", what is the name of the character that appeared 5 times in "the sea-coast"?
SQL: SELECT T.CharName FROM ( SELECT T3.CharName, COUNT(T3.id) AS num FROM paragraphs AS T1 INNER JOIN chapters AS T2 ON T1.chapter_id = T2.id INNER JOIN characters AS T3 ON T1.character_id = T3.id WHERE T2.Description = 'The sea-coast.' AND T3.CharName != '(stage directions)' AND T1.chapter_id = 18709 GROUP BY T3.id, T3.CharName ) AS T WHERE T.num = 5
