Smallville
S04E22 Commencement
Following a troubling dream, Clark heads to the cave to seek answers from his father, Jor-El. Jor-El cautions him that the crystals have been taken by humans, leading to a catastrophic meteor shower that could destroy Earth unless Clark can reunite the three crystals. Meanwhile, Lex assists Lana, who is suspected of murder, but soon betrays her in a bid to seize her Kryptonian stone. As chaos approaches, Chloe and Lois search for Lana while Clark works on piecing together the stones. Additionally, Jason returns, complicating matters for the Kents.
