Call me gullible or whatever, but if the initial deal was worded the way Linh says, I too would interpret that as "you can lot BB item if it drops on another orb, in exchange for the shank off your orb". Meaning the shank would be considered as payment for the BB item, and therefore Linh also had to go last. And I can't help but think that's exactly what happened here really. Luckily, gullible or not, I wouldn't find myself in a situation like this as I never ever do KS99s with people I don't know.

No doubt though, if you go on a KS run like this with people you don't know, make 100% certain the lotting rules are absolutely impossible to misunderstand/misinterpret.
