He's always saving her.
Logan looks back at Beaver in shock before returning his attention to Veronica, inching closer.
Logan : Look, you are not a killer, Veronica. Give me the gun.
His hand is nearly on the gun. Beaver just watches. Veronica cries hard.
Logan: You're not a killer, Veronica. Give me the gun.
She finally drops her arms, letting him take the gun. He wraps his arms around her as she sobs. He rocks her, glancing at Beaver who has made his way to the edge of the roof. He looks down. Logan buries his face in Veronica's hair, comforting her. He looks up again, just in time to see Beaver hoist himself over the low wall on the edge of the roof. Logan lets go of Veronica and strides a few steps forward.
Logan : Beaver, don't !
Beaver turns around to face them.
Beaver: My name is Cassidy.
Logan: Cassidy, don't.
Beaver: Why not?
Veronica says nothing. Logan struggles and can't find anything to say either.
Beaver: That's what I thought.
Beaver takes a step back and off the roof. Veronica walks forward and back into Logan's arms.
