Obligation reduction:
I think I already reduced Obligation (Keva's, Grayson) slightly

Keva reduced Obligation by 2 for cracking Fyr's signal's electromagnetic signature
3 XP for coming up with a crazy complex plan, 3 XP for securing more medical supplies for Varonat, 2 XP for yelling “It's a Trap!” in an appropriate fashion (and for escaping the trap), 10 XP for successfully executing the plan, slicing the hyperdrive, and presumably getting Kaltho fly into a sun. Total XP=18
Reduced Obligation by 20 or so (check out the Group Obligation Chart)
XP: 5 for figuring out Kaltho's role 5 for finding the tainted food, testing it, and notifying authorities 3 for returning Khan Vane to town with the roots 3 for avoiding a fight with the townsfolk =16 XP total
Obligation: -2 Slenahn's Betrayal Obligation -3 Slenahn's Family Obligation
AD-87 has improved his reputation in Tropis-on-Varonat, and they no longer despise him just because he's a droid. Grudging respect, perhaps, though not trust.
The rest of the party are regarding well - 2 boost to Charm & Negotiation, 2 setback to Coercion.
You are set up to possibly remove Kaltho's Obligation; either through admitting you stole it and offering to work the Jewel off or returning his credits, or by dealing with him/the theft in another way.
Another Obligation has been rolled that will allow for a minor reduction of another one next session. If you take advantage of these opportunities you might be able to spend XP at the end of the session.
