The Valid's van never got completely out of the building.
The debris, chunks of fallen warships mainly, became projectiles that slammed into the van's hull.
One chunk of warship, the size of a washing machine, smashed through the van's hull to enter the van itself.
Niki stood closest to where it went through.
It would have torn her in half...
if Trevor, lightning fast, hadn't pushed her aside to take the brunt of the impact himself.
Niki had just enough time to yell, "Trevor!" before Estelle grabbed them both to shove them against Noel just as the van shattered to pieces around them.
