The one that instantly jumps to mind is Alison-Roark-Marie, from Alison's Holding.
I was playing Alison, the hardholder. Parthenia was playing Marie, the brainer. Roark was one of my lieutenants in my gang, and Marie's kinda-boyfriend. When Vx opened a session with "Marie, Roark comes in all happy. He's all "Can I get a bath? I just blew up that expletive barge, and I'm covered in goo.", it made me groan in frustrated appreciation. Roark, the NPC, had just committed an act of hostility against a local slaver I was trying to avoid. And I couldn't just ride him out on a rail, because Marie actually cared for the lump. Plus, he was my lieutenant, and those were getting scarce. What to do, what to do...
Here's another, with Keeler (gunlugger), Twice (NPC medic) and Rose (maestro 'd):
Keeler's been shot, and she's in Twice' lab, unconscious and in need of care. Twice is holding back a bit, unsure what Vega's (hardholder's) orders are, since Keeler's been killing people without Vega's authorization (while possessed! It's not her fault!). Rose offers Twice sex if Twice will just fix Keeler already. Twice goes for that (natch!), but this puts Keeler in debt to Rose, and complicates Keeler's relationship with Vega even more. *sigh* Life is not boring!
Most recently:
Amanual (savvyhead), Voice of Eos (NPC whatever-the-heck), Rose (hardholder), Mox (angel). Amanual has found a way to get up to where VoE broadcasts from. Cool! After some fiddling, Amanual figures out how to over-ride (or maybe ride along?) on VoE's signal, and gets in touch with Rose via an odd bit of sparkle that Mox picked up in the room of the NPC crazy-preggo-ladies. Suddenly Rose and Amanual can talk! But Mox has no clue what's going on, because Amanual is talking to Rose's brain, and Rose is talking out loud. A hilarious scene of misunderstanding ensues. Then just when Amanual is about to tell Rose something actually useful, VoE realizes she's piggy-backing on the line and switches signals. Ergh! Later, Amanual watches as Keeler heads into a potential ambush...
Because Amanual (savvyhead) made a deal with Vonk the Sculptor (NPC) that Rose (hardholder) would welcome Vonk and his crew to the (relative) safety of the Luxor if Vonk brought enough tech and jingle along. Rose didn't authorise that At All, but here they come, through a hail of bullets rained down by VoE! Crap! And Keeler doesn't want to see civilians die within sight of the Luxor, plus they are bringing a busload of useful stuff, so she rides out with her crew, towards said potential ambush. Thank goodness for Rose's lieutenant (NPC) who was in communication with Keeler,and between the two we could pinch the shooters. We still woulda maybe lost, except Amanual found a way to watch the action from VoE, and discovered that VoE was puppet-stringing the shooters! Yikes! So Amanual hacks frantically for the right codes to turn off the shooters while Keeler scrambles to get the refugees through, and every so often VoE cuts her out and she has to hack back in! Casualties were within reasonable limits, but it woulda been a bloodbath. And now Rose has to deal with Vonk et al, and Keeler and Mox have to deal with wounded folks, and Amanual's still up/on/in VoE, plus who the heck keeps stringing up bodies in the ruins?
