In the premiere of Heartland season 14, Ty dies after suddenly developing a deep vein thrombosis (the result of a gunshot wound, though it can also be caused by playing video games). The repercussions of his death are continuing to impact season 14 as it progresses. Season 14 has yet to conclude, but nevertheless, the weight of Ty's death is unlikely to be resolved tidily in just one batch of episodes. Resultant complications, therefore, are likely to continue over the course of season 15 as well.
Further complicating things is the fact that Amy and Ty have a child together named Lyndy. Thus, how Amy will now raise Lyndy in light of Ty's death is likely going to be an ongoing plot point in season 15 and even beyond, should the series continue.
Also key in season 14 is Amy's sister Lou taking on the office of the mayor of Hudson, the town in which the series takes place. Meanwhile Georgie, Lou's adopted daughter, is interested in entering the Olympics as a trick rider. While developments that have yet to occur in season 14 may alter these characters' storylines, from what we know now, they're likely to persist in some form or another into Heartland Season 15.
