Mercer will not be sneaking any weapons in to the meet. The load out is strictly in case drek goes sideways between the van and the lobby, or if anything seems concerning while in the lobby. Once in the safety of Duncan's offices, Mercer is fine with disarming himself. He is concerned that an assault on the meet might be made, but he knows Duncan and Duncan knows him. Mercer's confident that he'd be armed before any force could make it through the lobby security, or he'd be invited to flee in whatever Plan B Duncan has if it looked like the fight was lost.
Eli's stuff - Unless Nico's selling the stuff on consignment, the zekes already have their money, so if they got deals, we should buy. Like Tec mentioned, there would be a certain justice in using Eli's toys to get revenge on his killers, but the risk is that these are trojans just like the painting. If it fills a tactical hole, then it's worth the risk. If it's just a nice to have, then we can pass.
As for the missing van, they probably kept that so that they could use it in our meet. Or it was hopelessly destroyed in killing Eli. My money is on the former.
Mercer will have no knowledge of Eli's stuff as they have never met or even talked. So any response to the list of gear Nico is offering is completely up to Achak. Mercer would recognize that it came from a Hunter by the sawdust weaponry, and thus recommend treating it with suspicion, but that's about it. If he thought about it, he could probably connect the dots and realize that gear from a Hunter showing up on the market right after Eli getting geeked were likely related.
The price for the painting is plenty fair in Mercer's mind - it is a cash sale, the sellers are remaining anonymous, the painting has a most likely illicit past, so its value takes a dive as it is unknown who may come looking for it, etc. And really, when dealing with "facilitators", it is common to only get 10-50% of the item's worth, usually closer to 10%. If it were worth 10m¥, then Mercer would be displeased with the offer, but I suspect that it's worth less than 5m¥. Not that Mercer would be opposed to negotiating up, but he wouldn't expect to move the price more than about 10-20%. However, Achak does bring up a good point that Duncan might be able to fetch a better price with the redaction of Sister Rebecca's restrictions, possibly getting up to double the price. We'll see what Duncan thinks, and Mercer will defer to his judgement.
Mercer will also look around as they approach Duncan's offices, and he will run his ultrasound all the way up until after they enter the library. Also, he will analyze the smell of the fried chicken to try to identify the recipe so that he can compliment him on some aspect of it. Chances are, he'll just comment on the real honey (I assume it is real), but he feels that if he can detect some otherwise uncommon herb or spice that was used in the preparation, the comment will carry more weight.
Perception (outside Duncan's) [Int 5 + Perception 6 + Visual Spec 2 + Vision Enhance 3]:
16d6t5 3Perception (Olfactory) [INT 5 + Perception 6 + Olfactory Sensors 6]:
17d6t5 6The visual perception roll is pretty craptastic, and the +3 from the Visual Enhancement only applies until he gets out of the van, removing the ballistic mask prior. He doesn't lose any hits from taking it off, so it's also beside the point.
Which brings to mind a question. With the acid rain and known bad air quality, is it really out of the ordinary for people to wear masks when outdoors, and even when indoors? I have been meticulous about taking the mask off when in public, but it might be moot if it is typical to wear such items all of the time. Otherwise, Mercer would probably be interested in getting some glasses with VE3 and (flare comp or vision mag) [2,150¥ and Avail 7 or 8].
Additional shopping list items are:
Receiver Dongle - 400¥ and avail 3
Sensor tags (2 camera, 2 ultrasound, 2 motion sensor, 4 blank) - 1,240¥ (40¥ for tags, 200¥ x 6 for R2 sensors), avail 5
I'm tempted to get some Full Body Armor, just so I don't look like the soft target among the crew, but considering the availability and the cost after getting it modded, I'll just wait for some to become available another way (loot from an opponent or maybe Flickr's set if he meets an untimely end). Everybody seems to have some, so it's only a matter of time...
I think that's everything.
