Peter was with the protagonists at the Amity farm at the beginning of Insurgent. Why is that?
I thought he was the one who tried to kill Tris in Divergent and whose body they found after he fell off (or was pushed off) higher ground near the Dauntless HQ.
Was he supposed to be a Divergent as well? He didn't have Tris' increased abilities in the 2nd round of training and I don't recall anything in Divergent indicating he was one of the Divergents.
Although it might not be clear from the movies, Peter requests that Tris take him with them to Amity at the end of Divergent, because he's afraid of being killed by the leaders. He willingly offers up information about the simulations in return for some kind of safety - it's worth noting that he's also injured with a bullet wound at this point, so he's in no position to defend himself.
Tris also saves him from from the combined Erudite/Dauntless army raid against Amity, which slowly starts the process of them working together - he's ultimately something of a coward, but comes to his own decision about his loyalties.
"I'm sick of doing bad things and liking it and then wondering what's wrong with me. I want it to be over. I want to start again."
