Robert was bored. It was written all over his face. The longer he had Voldemort, the harder it was for him to be pleased with anything remotely muggle-related. Without a shred of magic in the lab, it was hard for him to relate. He understood the necessity behind what they were doing--clearly possessing the cure would be beneficial to their health as well as promoting their control over the world--he was just impatient. He wanted the end result now; the fact that he couldn't magic them a cure made him more than a little cranky.
"I haven't a clue," Robert replied cooly, stepping closer to the glass that separated them from the disgusting creature on the lab table. It was hideous and dirty, revolting to even look at. His nose wrinkled into a sneer at it when it again went berserk trying to get a chunk out of the man in the lab coat. Part of Robert wanted it to succeed to give him a bit of entertainment. This particular lab coat man had insulted Robert earlier and he wasn't above petty vindication through shadenfreude.
The men sent another wave of shocks through the creature, and Robert rolled his eyes. "By all means, keep shocking the damned thing. That's clearly working." The men looked at him in confusion, resulting in Robert pinching the bridge of his nose. "Several PhDs and these morons might as well be poking the damn thing with a stick. What happened to the doctors we had last week?"
