Or at least the odds would have been looking grim, if it weren't for the fact that Bart was already returning from his run doing his appointed tunnel and chasing up behind Damian and freezing at his heel.
Bart peered down the split tunnels, listening for an answer to Damian's question from any survivors. He didn't hear anything.
"Everything was clear down that side. The tunnel stretches out for about a mile before it empties into a drainage gully. I didn't follow it, but I think it goes out to sea. I didn't see any people down there and no signs of damage. It must have come from further in." Bart said, inclining his head towards the tunnels ahead.
He glanced over at Damian. "Which way should do you want me to go?"
