Day 2,206

The walls of the great greenhouse are cloudier than an old man's cataracts, the life inside smothered by a dense fog of condensation that seems to drift throughout the rooms in one bulbous wave. It's said that it was designed to act as a prison for some kind of bioweapon but all we've managed to glimpse is plants and people.

They walk like they're drowning and with the air so full of water I suppose they might just be. We see the odd couple who aren't quite as people-shaped as you'd expect a person to be. I may not be an expert but fungal-looking protrusions and worryingly vine-like arms aren't in a general anatomy book.

Maybe somewhere along the way the line between person and plant began to blur. Maybe the bioweapon is some kind of spore and the poor people who built the great greenhouse had to seal themselves inside after becoming infected. Maybe they're the next evolutionary step.

Either way, the main doors have started to rattle and rumour has it that one of the side doors has been broken down from the inside. It's only a matter of time before we end up like them or worse, depending on what this alleged bioweapon actually is.
