Hey Daniel.
Agreeing with Garnet. It might be worth freeing up Bree's account again and then trying to send a coded message back to whoever. Find out who the message sender is, and then ask them what you can do on the outside to help them on the inside. They've obviously reached an impasse and need your help.
The reason I'm suggesting finding out who it is first, is to gauge whether or not you can trust them. It could be Alex, in which case I'd be very very wary, or it could be someone else, and I think you know who I mean.
I'm not going to make any suggestions on codes etc. that might give the game away. All 3 of you are smart (4 if you count d'Artagnan back at HQ
), you can figure it out. Good luck.
