Gus knew about Palmer , but he still went to his Freedom Center?
Gus knew about Palmer is working with the Master , last season he and Vaun had tried to Attack Palmer's office .
And he still took Angel to Palmer's Freedom Center ,
When reception ask everyone fill in the Forms about their blood type ,finger print and the etc .
Gus should figure out what was going on , and he and Angel were worry about the system and cop finding them .
In fact , i would worry any medicine given by the "Freedom Center "
