Morte's Stuff; The Lower Ward [contains spoilers]

As you may know if you've played Planescape: Torment far enough, when you enter the Lower Ward for the first time with Morte in your party, he is immediately kidnapped by some damn wererats. 

Well I've just gotten Morte back from that bastard Lothar by giving him the skull of the Silent King in exchange. But when Morte returned to the party, all the items in his inventory were gone, like Ingress' teeth, that magical reflective frame thing, and that magical water bottle that's always full of fresh water, and maybe some other stuff too...? 

What the hell! Where did that stuff go!? How can I get it all back!? Bastard Lothar! 

Please keep further spoilers to a minimum in your answers, please. (I hate spoilers! hehehehe)
