Glee Season 3 Episode 10 (01/17/12)
Sam joined the synchronized team this week in an attempt to win over Mercedes, while Finn learned a troubling truth about his father: he was dishonorably charged from the army and died in the States, not in the battlefield.
Elsewhere, Becky asked Artie out, but he turned her down as a girlfriend after one date and, oh yeah, we learned that Beiste eloped to Cooter.
