Barney has a daughter from a one night stand and she is called Ellie. Penny and Luke’s mother has been gone for six years and it is implied that she died from an earlier illness. Ted’s children advise him to ask out ‘Aunt Robin’, so Ted goes over to Robin’s flat with the blue French horn and the two connect immediately. An alternate ending omits the illness storyline.Ted and Tracy are shown meeting on the train platform. The scene ends with the train appearing in front of the pair and the yellow umbrella floating down the road. Both endings end with visual credits.
