Snowden could be in transit to an exchange point.
Think about it logically. Where is Snowden going to go? It was hard enough for him to find sanctuary in Russia in the first place. No other place would take him. And, if you don't think Russia tightly controls its borders you are crazy.
Bridge references the famous bridge during the cold war between east and west Germany where captured spies were exchanged by walking them across a bridge.
The exchange point now will have changed but the meaning of "The Bridge" is the same. Snowden may not be in Russia right now but he didn't leave on his own. He would be in the custody of the Russians. He is likely being transported to an exchange location where he will be traded for Stanislav Lunev. (Their disgraced traitorous spy for our disgraced traitorous spy)
Both can then be transported back to their respective countries to be tried for their crimes.
Q gave Snowden a Count down (T-minus) What do you think that was for? Meeting date? Also Snowden hasn't tweeted for over 10 days….maybe he can't
Snowden coming back to the US to face trial will EMBARASS the CIA >>> This is what I think is the payback
If payback is happening today….then maybe the exchange is happening today.
This is the most complete theory we have. Everything else is half baked. One way or another though we will soon find out.
