Smallville: Lazarus Preview

The return of Smallville to E4 has taken its good time, but the tenth season will finally begin airing next Tuesday, and having already seen Episode 1, Lazarus, I thought it would be rash of me not to give a few teasers as to what you can expect (as usual, very minor spoilers):
1. A certain suit makes another appearance.
2. There's no simple get-out clause for Clark's dilemma at the end of Season Nine.
3. An old foe makes more than one appearance- but you won't see him properly until the finale!
4. Opening the Book of Rao to stop Zod had consequences for the entire universe.
5. To what extents must Chloe go to in order to save Oliver?
6. Tess meets an intriguing young boy- and his story arc may not end how you think...
7. A dialogue sequence explains an uncertain fate left open since the eighth season.
8. "The only reason anyone calls you a hero is because you clean up the disasters you unleash."
9. A man from Clark's past holds an ominous message: "Jor-El was right- something dark is coming." But how can that man be alive...?
10. "I regret as a father. My faith in you blinded me to the truth. You will never be Earth's saviour."
Smallville: Lazarus airs on Tuesday 7th June at 9pm on E4.
