Here's a preview listing from TVaholic:
Smallville (The CW): New. Clark heads for my hometown of Seattle after a Zoner attacks a ship’s crew.
'Smallville' takes place in an alternate dimension from that of the main Toobworld. It's the same dimension in which we'd find 'The West Wing' and 'Mr. Sterling'.
But wouldn't it be cool if there were mentions of Seattle Grace Hospital ('Grey's Anatomy') and radio station KCAL ('Frasier') while Clark is there?
