How do they get away with all their clandestine meetings in front of seasoned CIA agents? Aren't they supposed to be training and living in a secure location?
Why didn't Ryan get thrown out when that guy told him he was being followed?
1) Alex was able to shake the "box" tailing her. Even though they knew EXACTLY where she was going, she was still able to avoid them without the slightest bit of trickery shown on her part. We should just accept that it wouldn't be hard for her to do so at will.
2) The rules of what gets you thrown out only applies to characters without last names. Established characters are allowed to be bad agents. Remember, Alex failed three tests already, yet she's still there. That was in addition to being late for yoga. She and Ryan could crap on the instructors desk and they'd be applauded.
