There are several references to Achak's backstory in the most recent post.
Rusty, a contact, is a troll gang leader. He and Achak used to be tight (like Connection 5) but then got competitive about Lola, who is another contact. Rusty, being an augmented troll with a better reach, got the best of Achak, which bruised Achak's ego (and face). I still have them at Connection 3 but there's some simmering resentment there. This is also the source of Achak's prejudice against trolls. In terms of Negative Qualities it's probably 50% Prejudice and 50% Phobia, but I had to pick one so I went with Prejudice. Plus, Phobia is from Run Faster, which rednblack didn't have when we were going through chargen.
Speaking of Negative Qualities, Holy Trinity is Achak's "dependent", representing the time he spends supporting the church and the tithing he does. He doesn't intend to stay long, just long enough to change clothes so that he's not walking around looking like an ATM in the Barrens.
This is also his "Gangland Hideout (Seattle, Squatter, Extra Secure)" lifestyle. I figure that it's a gang-run safehouse/bolthole and that most of the lifestyle cost (¥600/month) goes to the gang for protection dues.
I'll deduct ¥100 for the cab ride.
Achak's plan
1) Change out of suit and into full body armor, because Barrens.
2) Walk to the safehouse.
3) Formulate a plan with Sister Rebecca.
Achak will activate his qi foci for Sustenance and Cloak.
