The Mysterious Mr. Rana

There’s more to Rajiv Rana than we let on in In the Shadow of Ares.
What could he be hiding? And how did he really break his nose?

There’s more to Rajiv Rana than we let on in In the Shadow of Ares:

He paused, then added simply, “You’re quiet today.”

“Am I?” she asked coolly as she pulled on her immersion goggles and rings.  You’re part of it.  Margolis said so herself.  I know you’re hiding something.  That’s why none of the Green’s survey data from the past two years is available.

“Yes, you are,” he replied, noting the tone in her voice with a slight narrowing of his eyes.  “But, if you don’t want to talk to me, well, that’s okay.  We can talk again when you’re in a better mood.”

She yanked off her goggles and turned to face him.  “What makes you think I’m in a bad mood?”

He shrugged.  “Your…moodiness?”

“What?  Oh.  Well, maybe I am mad.  Shouldn’t I be?  I know you’re hiding something…” She stopped short when she saw his face suddenly become an expressionless mask.

There was an uncomfortable pause.  “Hiding?” he asked cautiously.  “What is it you think I am hiding?”

“I…uh…”

His dark eyes bored into her own.  “Go on.”

Me and my big mouth. “The, uh, the cavern…”  If possible, his face became even more expressionless when she mentioned the cavern.

“The cavern?  What is it you think I am hiding about a cavern?”

Think fast. “I, uh, I know you’re hiding something down there.  There’s…  something down there, isn’t there?  That’s why Grantham won’t let anyone go in?”

“Oh, that again.”  Rana pursed his lips and rolled his eyes.  The tension between them seemed to evaporate suddenly.  A little too suddenly, perhaps.

What could he be hiding? And how did he really break his nose?
