So I've been playing around in the Citadel/Nexus/Nova Prospekt-ish Jail and I've been trying out the pod system. So far, I've learned the Red switch sends the pod to the incinerator, and the middle button opens the pod. The other two buttons to the right though both seem to send the pod to Breen's office- is there a difference between the two? Also, what does the button on Breen's console do? I noted it turns green when the pod is in his office, but when I press it, it doesn't seem to do anything.

Thanks!
