The explosion from the grenade went off, causing the already slightly damaged building to shake.
Rayne landed on the ground, hitting her head against the back wall as she fell over. She opened her eyes to see Julian landing on top of her, shielding her from any debris that fell from the building as it shook and fell apart.
The walls crumbled first, followed by the floors. Julian held onto Rayne as the floor beneath them collapsed.
They landed with a forceful impact in the mailroom of the post office. Rayne watched in horror as the ceiling from the upper floors came crashing down on top of them.
Just as she thought they would be smashed by the crumbling building, one part of the concrete slab caught on the metal mailboxes, keeping it from falling further.
Julian was still hit by some smaller chunks of brick and concrete, causing him to bleed from a few open wounds on his back.
