《地球百子》第四季将新增两个角色，都是地表人。其中一个名叫Hugo，是身材魁梧、咄咄逼人的家伙，20多岁，具备天生领袖的本能。他对自己在A.L.I.E.的控制下所实施的暴行感到深深自责。 Clarke虽然击败了人工智能A.L.I.E.，但却面临一个无法战胜的新敌人——地球第二次毁灭。部分人相信末日即将到来，于是向所爱的人寻求慰藉；部分人不愿向命运屈服，发誓要战斗到最后一刻；部分人已经厌倦了战斗，他们宁愿什么都不做；还有部分人决定找个人做替罪羊。Clarke不仅与被洗脑的光之城追随者发生矛盾，还遇到许多新地表人，包括Ilian（Chai Romruen）——他坚信高科技是引发地球再次毁灭的主要原因，而天空人应该为技术的再次出现负全部责任。他在受A.L.I.E.控制时做了一些可怕的事情，他将尽力确保那些事情不再发生。Bellamy很担心Clarke，他不止一次对Clarke表示：不要事事都自己承担，也让别人为你分担一点责任吧。
