The print version of this week's TV Guide has a new photo and short story (speaking to writer Geoff Johns) on the upcoming Legion episode of Smallville. Kryptonsite has a scan on their site.
Before the Legion can help Clark, they have to get over being starstruck about meeting their idol. "They know Clark from the equivalent of history books," Johns says. "They're all alien immigrants like him and they look at how he pioneered the way for aliens to come to Earth as a haven."
