- Antagonistic avatars of good and evil fighting for the other characters’ souls.
- Reality revealed as virtual, as a kind of pseudo Freudian purgatory

Both finales aired at about the same time, so we’ll have to give the authors the benefit of the doubt and call it a coincidence. But whether coincidence or not, it’s funny how the «Ashes to Ashes» finale fit smoothly with the whole show (and its predecessor) while «Lost»’s deservedly raised disappointed clamours of varying degrees among the series’ fans. I do have a theory to explain that, but who wants to get bored.
