Efficiency! Ecological and environmental stewardship! Financial responsibility! These will be the founding pillars of your newly minted drug empire. You have everything you need and you don't intend to spend a single unnecessary moment on Planet Blue. Time to get back to Earth to start the long, difficult work of incubation, breeding, extraction, and chemical synthesis. Not to mention setting up a distribution network large enough to handle what's sure to be an incredible volume of demand for your new drugs. Not to mention a marketing campaign to figure out what to call this stuff!
The effect of the bug bite hasn't even begun to wear off. In fact, it seems like it might still be getting a little stronger. You wonder how long this lasts. With your heightened senses and intelligence from the unknown alien drug, you've no doubt you can sneak or, if necessary, brute force your way past whatever security personnel are currently stationed on the other end of the portal.
You quietly creep through the jungle until you find yourself at the gate to Earth. You take a deep breath and step through. You slam into an incredible sensation of acceleration with lights and colors surrounding you. You lose all sense of time and then you lose consciousness.
When you wake up, you are face down on cold cement. You hear a few startled voices around you, but you can't quite make out what they're saying. You look up to chart your escape route.
Everything is orange!
