|Blainie is one of 1,783 characters who have only appeared in one episode. Not much information may be available about him or her.|
Blainie was a sailor in the British Navy along with John Newton. In Amazing Grace he slept in the hammock below John. They served together during their first two year voyage. Blainie was the man to tell John that the Captain wouldn't grant John shore leave, prompting John to attempt desertion. It can also be presumed that because of the similar voices of Blainie and one of the men bringing John to the ship that one of those men may have actually been Blainie.
Any family he may have is unknown.
