Spoiler for raws:

I've seen the raws. I don't read in Japanese, but pictures were rather informative. Arita helped Akira save the stewardess. During escape he has fallen from a cliff, but was caught by Akira. Some talks, I think Arita wanted to die because of what he has done, but Akira, like a typical shounen hero declined to let him die. At that moment the nerdy guy started explaining that Akira was murdering other people because of head injury and changes in his brain. Akira was saved and they parted they ways.
I'm thinking about dropping this series after this. Head injury could be a good line of defense in a court, Akira was not sane when he has murdered other people. So he probably wouldn't be sentenced to jail, but secluded in mental hospital. Which actually means he would be imprisoned in a prison with nurses instead of armed guards. They let a murderous psychopath to go free.
