Question: is lexa in season 3 of the 100

Answer: Yes, In ``Wanheda: Part Two,'' attackers on a jeep turn out to be Arkers who landed separately. Their numbers have dwindled to 63 due to conflict with the community called Ice Nation and they accept Kane's offer to come to Arkadia, where the other Sky People live. Part of the group continue to search for Clarke, who has been on the run for three months due to now being a legend and subsequent target because of her defeat of the Mountain Men after Lexa's betrayal. This has earned her the nickname ``Wanheda'' (commander of death). Indra, one of Lexa's best and most trusted warriors, warns Lexa that the Ice Nation is marching on her; Indra is there when bounty hunter Roan (the banished Ice Nation prince) brings Clarke to Lexa, who sought to capture Clarke before members of Ice Nation did. Still angry at Lexa for her betrayal, Clarke is dragged out kicking and screaming while vowing revenge on Lexa.
