<p><span style="line-height:18px;">Is now known by Control. In the end most recent episode, (<i>Most Likely Too...</i>), at the end, we see Control looking at a file with Collier on it, showing he is a relevant number. And you know what that means? Control received his SSN, so she now knows he real identity. (unless it was a fake SSN, but I doubt the Machine would send a fake one)</span>

<p>But if the Machine gave Control Collier's real SSN, then she could easily figure out who he really is, and maybe blackmail him. (like threaten his family if he doesn't surrender)
