Brick:
Just checked over my sheet again and I completely blanked on Passing. It takes up a power choice, right?
Right.
Brick:
And just so I'm clear on it, if I don't have it does it mean I can't pass for human, or does it means I can't control my powers?
O Passing
You don’t have uncontrollable powers that mean you can’t function as a normal human without serious evasive action. If you don’t have this, discuss what the triggers are.
What it seems to say is that if you don't get Passing, you
CAN pass for a normal human,
EXCEPT THAT certain things might cause you powers to go out of control and reveal that you're not a normal human (think of stress or anger for The Hulk, or Cyclops getting his glasses knocked off, etc. etc.)
