# Jo is suspecious of the Slags. Find out about the dead bodies at the Ghost Farm and find out what happened to Karl.
Feeling a bit "suspecious", Jo will give you a month (31 days to be precise, just enough time to go to the Den and back on foot) to prove the Slags are not dangerous. If you've been paying attention you shouldn't need it; inform him of the fake bodies (you can also ask Vegeir about those) and Karl being in the Den, and you'll have paved the way for an alliance between Modoc and the Slags for 3500 xp, plus you can now tell Karl to return to his home. Jo will tell you about Gecko but not actually put in on your map, and you also get a one-time discount big enough to get all his stuff if you trade back and forth for a while.
If for some reason you can't or won't find out about the bodies or Karl, you can tell Jo you want out (same 700 xp as before), or tell him to attack the Slags. The latter will teleport you to the Farm, where the townsfolk make a more formidable fighting force than you might have credited them with. Basically you kill a few guards and ghosts, and then the game assumes that everyone else on the farm was killed too (if you go down the manhole, Vegeir will be there alone for you to deal with). You don't gain any quest xp for this, and it spoils your chances of saving Jonny. If you fail to inform Jo of Karl and the bodies in 31 days, the townspeople will attack on their own with basically the same results (if you go to the Ghost Farm afterwards you may find some ammo and stuff lying on the ground at the farm).

If you give Karl $1000 and then immediately ask him about the G.E.C.K, he'll offer you $1000 to sleep with him if you if you have CH 8. How does he afford it? (You can also steal the money back when he falls asleep. If you fail he'll run away when he wakes up, but you can end combat and he won't be hostile.)
