" Ack! " Karen looked at her chest only to see a knife protruding from her chest, the blood spreading to her white coat as she cough blood. She unbelievably looked at Fifth who looked at her expressionlessly as he retrieved his hand from Karen's chest.
" That's good. I will need you to disappear then. " Fifth said as he watch her fall in the cold floor, gasping as she find it hard to breathe and clutch her neck. Fifth look at her slowly dying calmly, " Today is a special day so I hope I can borrow your card. Hm? It's okay? Thank you, then goodbye. " He one sidedly said as he leaned and took the card on her pocket and leave the laboratory and used the card to lock it so no one would enter.
Before leaving, he took one last glance at the kids in the chamber that was dying and decided to leave them. All of them is already beyond saving, it's better to let them die here. He can't to anything but to end them together with this facility.
