The Dark Tower/Wolves of the Calla/YMMV


 * Fridge Logic - Nobody is sure whether Benny Slightman counts as a twin or a singleton, as his twin died young. How could an agrarian society with little access to medicine, in which infant mortality is expected to be high, not have learned that from previous raids?
 * Narm - The way the Ka-Tet, particularly Susannah, were so awed and amazed at Roland's ability to do a solo line-dance ("He knows so much.") was just laugh-out-loud ridiculous, the low point in a book that marks the increasing fall of what started out as a pretty good series.
