BUR #2371 has been approved by @evazion.
create alias pale_face -> turn_pale
Reason: The two tags "turn pale" and "pale face" basically mean the same thing: a blue tinge on the face (or vertical lines if monochrome) as a form of negative reaction to something.
Also, (excluding the incorrectly tagged pictures) the contents of both tags are almost exactly the same.
EDIT: The bulk update request #2371 (forum #164135) has been approved by @evazion.
