anyone know if the following are 'tributes' to other series?
in S2, Ep. 4, "Comrades," there are Russian sisters, Kayta & Elena, is that a reference to Alias?
in S2, Ep. 13, "Bad Breaks," Mike says, "...get some leverage," could that be a nod to the actor playing Prescott, who had a recurring role on Leverage?
in S3, Ep. 4, "Fearless Leader," the bit with the Greyhound, is that a reference to The Simpsons' Santa's Little Helper?
these aren't noted on their pages on here, just wondering if anyone had heard it for sure from the producers, one way or the other?
thanks
