Birth of a monster...
By the time the medical team got to the scene the face-hugger was already well established. One medical officer would try and cut the creatures legs away from the mans face which resulted in a splurge of acid which covered the medical officers hand. The acid gave off a horrible hiss as the plastic of the gloves the officer was wearing melted into the officers hand. Screaming in agony he proceeded to try and wipe away the acid blood by using his other hand. This did nothing but exacerbate the situation.
As his colleges watched on the acid continued to bubble into a horrible red froth as flesh and tissue began to melt away. Unable to do much else they bandaged the wound and stretchered both men into the back of the emergency vehicle and headed back to the main complex.
As they placed the man on the table the doctors struggled to find out what exactly was attached to the mans face. As they looked to his wife and two children waiting outside they continued to run tests on their subject. The man with the acid burns wasn't doing much better. His right hand which took the brunt of the acid was completely irreparable. It would have to be amputated, the other would need extensive skin grafts to repair.
As the humans hurried and did their business of prodding and poking at the creature they were unaware of the situation happening within the hosts chest. The face-hugger would tense and hunch before slumping back, this would continue as it pushed the egg down the throat of its host. The mans throat would bulge slightly giving the indication of swelling but it was not so obvious as to indicate a foreign body within. The tip of the egg tube itself now oozed some of that acid blood against the wall of the hosts windpipe making a very neat hole into the chest cavity of the human.
Once a passage had been made the last few pushes created an amniotic sack, as it bulged between the lungs and the heart like a balloon the embryo would be squeezed into it. It would hang in the fluid for a moment longer before it would give a final push, blowing the balloon like sack completely into the hosts chest. The last thing the face-hugger would do was to detach the egg tube. This inevitably would kill the creature but heal the hole in the windpipe as the alien flesh would contract, creating its own flesh graph over the hole it had created.
Watching from beyond the large glass windows of the medical bay a little girl stayed and watched her Father as her Mother and Brother wandered over to talk to one of the doctors. As she observed her Dad on the table, the creature on his face began to twitch. Horrified to see it move she gave a small squeal and ran towards her Mother. While she tugged on her arm and pointed towards her Father in the medical bay the doctors all turned at once to watched the Alien creature slowly dismount the mans face, shudder and then fall to the floor.
It's legs curled together like a dead spider, its tail now limp. The face-huggers short life was over, but the life of the monster which resided within the mans chest had only just begun.
