The Waitrose kids and the Morrisons banded together to leave in the morning and to make it to the palace by night. Their group of kids in total equaled 80 with the small kids in the middle, and the bigger and better fighters making a ring around them. They started marching from Waitrose to a new beginning at the palace. The group with Arran and Blue at the front marched for awhile until they ran into a massive army of grown ups at the top of the hill ready to charge. Before the grown ups were always stupid and dumb and could never organize a real attack. But they some how evolved and started to charged the group.
Arran and the best fighters move to the front in a fighting position but Arran was was after his bite in the neck started to make him sick and it slowed the group down. Lewis and some other fighters protected the little kids in the corner and had to stop them from running around in panic, they had to hope the main fighting force would hold out. Meanwhile Arran looked around and saw that his fighters were being overrun and slowly being picked off one by one in the large numbers of the grown ups. But his team was able to fend off the grown ups and send them running away.
Arran was angry and wanted to chase them down to kill every last one of them when he was shot by an arrow through his lung and collapsed. A girl named Sophie and her survivors came across from the hill as Arran was slowly dying. Everyone was weighing the options on what they should do , when Achilleus became impatient and pulled the arrow out of his lung. Arran then couldn't fight anymore and died. They lost many other kids and decided to burn them in honor and to not let the grown ups eat them.
Small Sam left from Waitrose with food and water that Callum gave him and headed on until he hit got a flat tire on his bike and some grown ups chased him into the subway station. It was dark and Sam was alone. He traveled everywhere underground hoping to find a way out and evading grown ups, until a man named Nick saved him and brought him to his home in a train with his wife Rachael. They somehow survived the apocalypse and took care of him giving food and a bed to sleep in. But they are not who they seem when Sam is asleep they handcuff him to the bed.
Maxie's group presses on into the night when they travel through a park and were ambushed by creatures from the trees. They fended them off but it wasn't enough after they lost 5 more kids who laid dead in the tall grass. They spent the night in a garden and were down to 53 kids left in all 3 groups together. They pressed on not seeing many grown ups when they stopped at some clothing stores to go shopping.
This is Oxford Circus in London. Maxie and the group go shopping in this area to get nice clothes for the palace.
