Homecoming (S10E04)

In a record-breaking event, the series' 200th episode brings back some familiar faces like James Marsters as Brainiac. In an attempt to cheer up Clark, Lois convinces him to attend their five-year high school reunion in Smallville. A visit back to the home of the Crows has Clark remembering old times with Lana (past series star Kristin Kreuk) and Chloe, while Lois is furious that no one remembers her five days as a student. Brainiac 5.0 (Marsters) uses his Legion ring to visit from the future and takes Clark through his past, present and future. He shows Clark what really happened the night Jonathan died, Oliver's current pain and Clark's future at the Daily Planet with Lois and his role as Earth's favorite red and blue superhero.
