In We Are Grounders (Part 2), Sinclair explains the workings and possible consequences of returning the Ark to Earth to the inhabitants of the Ark, explaining that some parts of the Ark will be destroyed when entering the atmosphere alongside the people inside. After everyone is strapped in for the descent, Sinclair tries to remotely separate the Ark's stations from the Earth Monitoring Station with explosives so they can use the Ark's thrusters to blast them off towards Earth, but the remote detonation fails and Sinclair informs Jaha that someone will have to manually detonate the bombs and stay behind. Kane volunteers and is ready to leave. Sinclair notes that he will have one week of air left on his own. The Ark suddenly shakes as the bombs explode as Jaha has gone to the Earth Monitoring Station to manually detonate the bombs. The station separates from the other stations, which start heading for Earth as the thrusters activate. Sinclair survived the crash landing of the station Abby and Kane were in, and is now on Earth with them.

In The 48, Sinclair first appears along with Abby and the rest of the survivors of Alpha Station's crash after Kane shoots and kills Tristan. Kane then has a short discussion with Bellamy and Finn, before ordering Sinclair to take Sterling, Monroe, and majority of the surviving adults back to Alpha Station. Later, when Kane returns to the crashed station, he discovers that Sinclair has named their new home "Camp Jaha". Sinclair then says that there has been no word from Jaha and calls Kane the new Chancellor.
