第2話: メモリーセルの幻と小腸での待ち伏せ
"Acquired Immunity": Memory Cell receives visions of destruction and believes he has gained the power to see the future. The Parotid gland gets invaded by the Mumps virus. As the immune cells fight them, B Cell cannot create antibodies without Memory Cell's information, but Memory Cell is obsessed with trying to see the future again and is useless. When B Cell strikes him in frustration, he realizes he was actually seeing his memories of the past when the body received a Mumps vaccine. B Cell creates antibodies from the information and wipes out the virus. Afterwards, B Cell explains why it took him so long, resulting in the cells beating Memory Cell up. "Peyer's Patch": U-1146 takes AE3083 and NT4201 on a tour of the small intestine, but Killer T Cell berates him for not focusing on his job. The small intestine gets invaded by Campylobacter bacteria who take an Intestinal Epithelial Cell hostage. The white blood cells surrender and give in to the bacteria's demands to humiliate themselves. However, they were slowly luring the bacteria to a Peyer's patch where the bacteria are ambushed and destroyed. Afterwards, Killer T Cell apologizes to U-1146, but retracts his apology when U-1146 realizes he forgot about AE3083 and NT4201 and rushes over to check on them. (Source: Wikipedia)
