A Killer T cell deposited a Helper T cell directly into the latter's office, mid-drill. The two disparate cells immediately began to argue. A Dendritic Cell intervened, explaining that despite their current distinct roles, they had once been classmates at Thymus School. And not only that, but they had been vastly different individuals then! What had transpired between them during those grueling training sessions at Thymus School, where only a meager two or three percent of cells survived?
