"We haven't figured out how to safely scout his world yet," Edward says, folding his hands in front of his face. He's doing a great Gendo impression right about now. Except without the shiny glasses. "But we have to be prepared for a couple of things. One, that his Edward may not even be alive anymore. Something- anything, we don't know what- could've happened to him, and that's why Envy's in the market for a new pet.
"We also have to be prepared to accept that he may be too far gone to rescue. If Envy's got him broken enough, he may suffer from Stockholm Syndrome and taking him away would be tantamount of killing him. We could theoretically call in a telepath through the Gate to erase as many memories as possible so that rehab is possible, but we can't guarantee that. Nobody's talked to the Gate about this yet.
"Beyond that, I highly recommend that no Edward travel alone for awhile. Keep an Al with you, or someone else who's a fighter. And for gods' sakes, keep a PIN on hand at all times. And your pendants or rings."
