Now, this really is a daft episode. But it does establish a connection between the Kryptonian stones and Lana's ancestress. Lionel seems genuinely to have reformed and now to be seeking wisdom instead of his own aggrandizement. But we still do not know how he was released.
Dr Swann dies. How did he get Kryptonian tech? Well, it seems to have been lying around on Earth for a long time. His assistant has absconded with a stone, Lana has one and the other is back in the cave. I think.
Lana and Clark fly to China in a plane where they have their own lounge. OK.
