After Ski Lodge, even though I dislike the eps and try to pretend they never happened (except the Lucaya hug and firelight comment. that stuff happened.)
Something happened the night before Lucas chose Riley and after he chose her Maya and Farkle decided to run away together.
Five Years Later they come home again, but they bring a surprise with them. A five year old little boy.
Lucas and Riley broke up after Maya and Farkle ran away, but they stayed close friends. Now they are dating other people, but will Maya and Farkle's return change their feelings? Or will the little boy?
