I just realized something...
Didn't Hameal give us something when we were interrogating MoMo? He gave us two things, but one of them caused the person being questioned to keep talking despite themselves. I don't think Mitch ever gave it back. I am looking for that post and I'll let you know if/when I find it
---EDIT---
Found it!
Details are in the spoiler section. I also found
a tiny bit more detail
But I can't find is if we ever gave them back, and believe me, I looked. Doesn't Mitch still have them?
---EDIT 2---
NVM, I found it. We did give them back to Hamael. Darn it...
