Question: I don't remember a hint on the movie how Jason Bourne found the home of [Jarda](http://bourne.wikia.com/wiki/Jarda), the only other living Treadstone assassin. Is it mentioned somewhere or are we just supposed to assume that Bourne simply used his amazing resourcefulness to find him?

Answer: 
There is no explanation. I really cannot see the CIA allowing their Treadstone assets to know each other's addresses. I can see thing giving Bourne's Paris address to Castel and the others when they wanted him dead. But alive? I don't see it. In fact, the movie never hinted that the Treadstone assets worked together. The Professor didn't seem famliar with Bourne when they met in Southern France.

By the way, Jarda was the German asset (from Hamburg) in **"THE BOURNE IDENTITY"**. Manheim was the German asset (from Munich) in **"THE BOURNE SUPREMACY"**. The 2002 film never hinted there was a fifth Treadstone operative, especially since Conklin had made it clear in "IDENTITY" that he wanted all operatives in the program to go after Bourne.
I always thought the Treadstone operative who killed Conklin on Abbott's orders in Identity and the Treadstone agent Bourne tracked down in Supremacy were the same guy. I don't understand why they had two different characters in these roles; it would have tied it all together nicely.
