Allegiant alternate ending
Begins where Tris and Caleb are caught by the guards.

I watch as Caleb throws on the clean suit, and run towards the weapons lab. Before I can even process what is happening, I run after him no longer caring about the guards. As I get closer, I hear the explosives go off.

"Crap." I murmur under my breath. I stay where I am, knowing it is already too late. I turn around and run towards the entrance. The compound is empty as I run through it. I get to the door and bolt outside. I get further from the compound, but not that far. In the distance, I see a van driving towards me. I know immediately that it is the group Tobias is with. It pulls up across the street from me and the doors fly open. I see Zeke, Christina, Amar, and Peter before I finally find him. I stand up and immediately run towards him. He sees me just in time. I wrap my arms around his neck and bury my face in his chest. He tilts my head back just far enough to kiss me. It feels like I haven't seen him in years, but really it has only been a day. I have almost lost him too many times. He is never leaving me again; I can't bear to have to live without him. When we pull away I have only one thing to say.

"I love you. Never leave me." I cry.

"I love you too. I could never leave you." He says back. I stand up on my toes and kiss him again.
