The side chat.
You have more or less three options in this case:
Considering that at one kilometer out you usually are already starting your landing approach and assuming that the area is not safe, land where you were planning to. Mister Hol-van-Pluto-LZ probably will get out at that point. If he doesn't, check out LZ Hol-van-Pluto and decide wether you can go there. If you can, you are now able to offer him to go there after the others got off.
Assuming you are a good pilot and you are not currently being shot at, you can attempt to come around for LZ Hol-van-Pluto. Or you offer him to go there after the LZ of your choice. Involves looking at the map, not ideal halfway into an AO landing.
Screw that guy and his LZ that he marked in the wrong damn channel, this is your helicopter.
