Darkness on the Edge of Town - S1-E22
Character mistake: At one point Felicity says, "There's at least a teraflop of data to go through." Felicity is a computer genius, so she should know that a teraflop is a measurement of processing power, not data storage. She should have said "terabyte."
Chosen answer: "C'mon Doll" by My Goodness.
