They have come up with an ending - it's just that in the second season, they didn't know if they were going to last for another two seasons or another ten. They couldn't exactly reveal all their answers and then find out they'd been re-commissioned, could they? So they had to drag it out a bit instead of getting on with it, like in season three.
