I genuinely can't stand any of them Stephen always looks absolutely terrified and the most nervous out of all of them, Rachel when Claudia was explaining the mission was the only one who was clearly really trying to pay attention, whilst the others were all in shock but no one noticed.
Also back to the FBI 'profiling' training she had, I'm pretty sure FBI profiling isn't how she described it, it's actually creating a picture of a suspect they don't know.
