The One with an Imitation Ruby, a Teenage Bride and a Shotgun . Here comes the Bride S4 Ep 12

Walnut Grove is the new home of Father and Son duo: Adam and Luke Simms.  One his first day of school Luke meets Nellie Oleson whom is immediately smitten with the young man.  Not only that but her usual solution of getting people to like her, bribery via candy, is not going to work forcing Nellie to step outside of her comfort zone.  Speaking of comfort zones, Harriet Oleson is also out of hers when she finds out her daughter is in love with the son of a Pig Farmer. Miss Beadle doesn't seem to mind the pig farmer occupation, in fact she finds any reason/excuse to head to the Simms farm to talk with Adam.  And like father, like son, these men end up with a woman by their side. While Miss Beaddle is reluctant to accept the marriage proposal that was offered to her, Nellie and Luke....sell a sow, steal a buckboard and elope to Sleepy eye to find the nearest Justice of the Peace and get married.  Needless to say Harriet with the Shotgun (the widow maker) along with Mr. Oleson, Miss Beadle, and Mr Simms head to Sleepy Eye.  And while one marriage is dissolved, after a bit of hilarity,  a second wedding takes place.  Is anyone disappointed we didn't see more of the Ingalllas in the is episode?  With the parents away in Sleepy Eye, what sort of hijinks did Willie get into at the Mercantile?  How did we get to the beginning of summer with no mention of winter taking place?
