Actually, voss WAS stung, and the stinger was underneath a fingernail or toenail which is why it went undiagnosed for so long, resulting in such a lengthy period of illness during which he was unable to communicate.
Really. That's what really happened. Honest. No kidding. No shxt. The truth.
edit - Remember, voss is just an online persona so anything that happens to voss is a virtual event. That means it's not really a lie, just not something that happened in the real world.
