Fantastic episode that dives into Birkhoff's background where we learn that his name is in fact an alias and that his father plays a big part in 'The Shop' and the thorn that has been pricking Nikita and the gang all along. I thought it was a good choice to have Judd Nelson playing his father. Curious to see how this plays out now that his doppelganger has been silenced and if Birkkhoff will have his reunion with him. I loved watching them communicate with each other by way of hidden codes on the computer. Very cool. As for Owen/Sam, I'm still not convinced that he is back to being 'good'. There is still some ulterior motive at work and I fully expect him to try and back-stab everyone again.
