Which Characters Are Coming Back For 'The 100' Season Four?

Is anyone else just living for The 100‘s season four trailer?!

The entire thing has just majorly excited for the actual season ahead and we can’t wait until February to get here!

However, after we watched the trailer, it had us wondering just which characters would be returning and who wouldn’t.

We know that both Ricky Whittle (who played Lincoln) and Alycia Debnam-Carey (who played Lexa), will definitely not be back.
