.. How do I trap the culprit?

When you enter the hub, there's no sign of Ewan, but he's around here somewhere. (Maybe there's a secret bathroom behind one of those computer banks, who knows?) We just need to smoke him out.

Remember how you got him out of the way before? When he hears that temperature alarm, he'll run to the thermostat from wherever he is.

So go back to the thermostat and -- rats, he's put a lock on it. Ah, but he foolishly left himself a note in his lair as to the code, remember? Did you take a picture like I told you?

If not, the code is --

-- like this: #p-O 2 O
O 4 3
1 O 5 #p+

Set the temp to 80 and go hide like before (back, left, forward, left, curve right). But ... now what? We need to keep him in there.

Remember those firewalls? If not, after you hear Ewan stomp past, go to the entrance to the computer area (back, left) and look for a panel on the left wall that says "Firewall Controls."

The bay with the thermostat is B3. Push that button, and Ewan is locked in for the duration. Let's go see what he has to say for himself.

How do I gather the USB drives?
