Question: I loved the Flash on Smallville last season. Any chance we will see him again?

Answer: Kyle Gallner's Veronica Mars sked permitting, yes. According to Al Gough: "Kyle is in 12 episodes of Veronica Mars this season, but luckily, Rob Thomas and I are friends, and if we want him for an episode, we just need to give them enough warning to make sure we're not stepping on any of their plotlines with him."
