SPOILER!!!!! Lol but yeah I have a feeling he will pop his head in. What Im ready to see is what path they take when they pick up where they left off.....But they kinda hinted that Spartacus is going to march on Rome but there is another version of the story that has Spartacus going north to escape....I like the latter...Pluss Spartacus' body was never found....hmmmmmm
