You were created and became a new cell, you were besides other cell, it was kindoff a small town for cells to live inside of human's body, you saw killer t cells as cops or doctors, and some other cells being just themselves

Cell: damn, i'll hope i won't be next like that guy over there, that poor guy... points at cancer cell still alive being terminated by killer t cell

Cell 2: to be honest, it is hard to not get infected, nobody knows who's next.

T-cell: well we know, but we have too, we gotta keep the human alive somehow, he's the most important to us, that's what makes us alive too.

NK cell: runS around releasing gas at cancer cells working with T-cells

Cancer: just groans like a zombie, but is not a zombie i just want to exist...!
