Just an FYI, I read the Deep Scan description in the EP Core Rulebook. Aghassi will be aware that you have probed his head, and he is a dangerous guy to cross. At best, you can expect to get kicked out of the Office and be beaten to within an inch of your life. At worst, the entire office's security will crash down and your cortical stack would end up as a paperweight in an Oversight agent's office. Unless you can somehow make him forget that he got Deep Scanned after you do so or convince him that it was nothing, you will likely face heavy repercussions.
Also, since every piece of information you extract takes one action turn to do so, others will likely notice when you are holding his hand for ten seconds while he looks like he is in catatonic shock.
I'm letting you know because it could be dangerous to your character and it might not be worth it in the long-term. If you still want to do it, fine by me: we'll let the dice tell the results.
