Maybe the Train Job really wasn't important at all; it would explain why only two agents were assigned to it. I'm sticking with my theory was that it was a test of loyalty for Blake. Adam knew this and, out of friendship, gave her advance warning.

It's my theory that the laugh at the end of the "Black" Trailer is Adam expressing satisfaction that she's escaped.
