And, this one was no exception.
First; there's the obivous, real-life irony. Michael Rosenbaum, voice of the show's Scarlet Speedster, plays teenage Lex Luthor on SMALLVILLE.
Second; there's the contrast between Luthor being mentally fast enough to adapt to Flash's body and powers. While the reverse is almost fatally not-true!
Third; the look on Tala's face, at the end, when she realizes that Luthor is, indeed, back to his old narcissistic self. It almost makes me wish she could have caught on to the imposture sooner! Just so she could blackmail and/or mesmerize Wally-in-Luthor to act as her figurehead, while she becomes the real new leader of the LOD.
The only reason I don't give this a perfect ten? Hijacking a trainload of mere paper cash doesn't seem super-villainous enough. But, gold bars on their way to Fort Knox? THAT would have been a worthier target!
