Great work! Really glad the tunnels worked out (although from the looks of things down there, you don't want to spend *too* much time there). As for the trio in the medical facility, I didn't pick up that we should be scared of them... perhaps I've just forgotten something from earlier in the story?
Here's what I do:
1. If it's not already loose, use the tool kit to quietly open the hatch, but keep it in place to hide you. Wait for Fang to pace away from you, more toward the Wookie. When he's far enough away to give you time to exit the hatch, quietly do so, with your blaster trained on the wookiee's head. Hopefully they haven't spotted you and you'll catch them by surprise. Demand they drop their weapons, and tell them you want some answers about "the List" and why they think you can help them.
2. If we're really *that* scared of the security officer and wookiee, we wait. In four minutes they're probably going to storm out of there after laying a stream of insults on Blondie. It's unlikely she will leave with them considering how much they are at one another's throats. After you narrow the odds to 1:1, wait for Blondie to turn her back and move into the room to meet her as in scenario 1.
3. If they all leave together and we're still scared, count this as a blessing and retreat to the previous lift station and make your way back to Crate at Dex's... he might still be having dinner. Ask him if he's ever heard of "The List" and if he might know of someone who knows about Imperial involvement on the station. Failing that, retreat for now and prepare to confront Blondie on the job... go to the bar later and ask "So, do you want to tell me about the List, or do you have to have your goons handy first?"
I prefer option 1 as it gets more immediate results, but it sounds like we might have gotten our big toe into a very deep pool of secrets, and we might not want to dive in until we know exactly how deep things go.
I don't know, Quazar, you have me in a bit of a pickle here. I can't really come up with a solid plan of action here...
