Reverend Brian Darling is the middle child of the Darling family and is revealed to be the child of Dutch George instead of Tripp Darling.
Brian Darling is an illegitimate child of Dutch George and Letitia Darling who was conceived during their years-long affair. This means that he is the younger paternal-half brother of Nick George and the younger maternal half-brother of Karen Darling.
This means that his half-brother was dating his half-sister. Boy, that is sick!
