In most of the begining of the game Cloud has some sort of inner person speaking to him. Is this the Jenova cells in him speaking to him?
Also, notice how in the begining Cloud talks about him being in SOLDIER but later on we learn how it was really Zack who was in SOLDIER while Cloud was just a regular Shin-Ra guard. Is Cloud having these hillucinations because the Jenova in his body made him share memories with Zack or did he just say he was in SOLDIER to gain attention and help from his friends?
