Feat for inquisitive rogue? Our DM is asking us to write a quick backstory, and to add a feat as long as it makes sense. I'm still flushing out my backstory, so I can tweak it to include most things.

Playing an inquisitive rogue, LVL 6. This is my first time playing this subclass. My perception and insight are already 10 and I have an 8 in investigation and sleight of hand. We're in a detective guild and my background is faction agent. Other party members are a cleric, bard and fighter. Was considering sharpshooter, or lucky as this is a side campaign, to play over zoom, and I don't think we'll make it up to LVL 11 for reliable talent. Any ideas?
