The fourth season somewhat resurrects a presumed-dead ship from the earlier seasons: exes Steve and Nancy. For a while, it seems like their relationship has settled into a comfortable friendship, but there are a few too many lingering looks in the new season for them to be "just friends." Other characters also comment on the possibility of the exes reconnecting. With Jonathan and Nancy struggling with long distance (and, unbeknown to each other, possibly making college plans that will keep them apart), it's not out of the realm of possibility that Steve and Nancy might wind up back together.
On the other hand, a romantic reunion could easily feel like a character regression for one or both of them — and there are theories that one or both of them might not survive the show — so that could throw a wrench in the works.
