Just before going into the Planar Sphere, I talked a guy who standing in front. He was a kind of a con man tried to sell the Sphere to Minsk for 500gp. You need to approach him yourself, and it's nothing to do with the quest (I don't think).
Minsk's answer was great!! Like, "Boo says the Sphere is too big to fit into my pocket, and if I cannot carry it around, there is no point to buy it." It's such a clever and funny answer only Boo can come up with! I wonder there are any more like this? I really don't want to miss them!!
