ok about the jade/rain quest i did that before i beat konquest. i came back to edenia and i came around the tent and she wasnt there (after you tell rain about the cave she is no longer inside the tent but like 30 yards in front of it.
however as i was heading there to collect lui kang, she was there standing over rain's body. she was also inside the tent lol. i 'asked her why' and she told me not to tell rain about the ambush lol. i talked to her at rain's body now she is training me. hehe
