Smallville Season 10 Teasers

Rumour has it, Smallville: Season Ten will begin its run in the UK on E4 not long after the New Year (Channel Five are taking over running Glee, so there's a gap for E4 to do something...). In that case, I've looked around on the web for some good teasers to sate your appetite for the show's finale. Here's just a few hints...
10. Clark pops the question!
9. Tess has harboured secrets from Clark before, but now she's got more than one which the future Super-Man won't be happy about...
8. "Something very dark is coming" So says Jonathan Kent- but wait, isn't he dead?
7. After the Series 9 cliff-hanger, Clark hangs between life and death in a cornfield- but who else will he find there, and how can he be revived?
6. Carter Hall and the Justice Society make multiple returns, as does Aqua-Man
5. Why is Chloe Sullivan only in a few episodes this year? Find out in Episode 1!
4. An old foe's actions has dire consequences in Cadmus Labs in the season opener.
3. Martha Kent is also back in Smallville- but what brings her there?
2. Kara's also back, but for a very different reason...
1. An alternate universe in Episode 10 heralds two dark words: "Clark Luthor"! It also proves a means of return for Lionel Luthor- he comes to our own universe!
