Meteor powers include telekinetic glass-shattering and are inheritable but this power appears just in this one episode, I think. Clark tells Maddie that she can trust him - but everyone can't trust Clark. A piece of artwork at the Talon becomes a plot element and Belle Reve is mentioned again.
The main on-going story line is Lex and Lana - and Chloe's misguided interference. She should have either kept out of it or spoken to Lana, not confronted Lex. Why Clark doesn't get together with Chloe is beyond me.
Lois becomes Martha's chief of staff. I still don't get it that Martha can take Jonathan's Senate seat without another election. Lionel is in London so he is not around this time.
