(wow this is a lot darker than I expected, but we can go this way)
(though remember you are connected to the kaiju so when you are calm, they are calm)
(one final thing the Kaiju can talk to the kids, through telepathy)

Alex all of a sudden open his mouth and shot out atomic breath that destroyed the sleeping pod cover. He then crawled out and jumped off landing on his feet below the crystal. The nurse Kim said "Alex? is that you?" Alex was confused and said "yeah it's me but not me at the same time. Alex then looked at a mirror, his grey eye now looked like Godzilla's eye and his right arm was made of crystals similar to the ones holding up the pod. Alex said "what the hell was in that bag" The nurse picked up the bag and noticed that the labeled was covering another label. She remove the top one and her eyes widened. "I just injected you with DNA from Godzilla" Alex held his head and said "that explains the weird memories." Godzilla suddenly stopped attacking the wall and began to look around almost as if he heard something. Then Godzilla said "who is there?" Alex froze and said "I'm Alex, are you Godzilla?" Godzilla said "you are correct, but how are we able to talk and why is it that I can see images of a human standing in a white room with me." Alex said "that's because I'm standing in a white room with a human nurse named Kim also, i'm human."
Godzilla said "I demand to know why we can talk"
Alex said "beats me"
