Let me just say, welcome to the fandom! :)
Yeah, once Children of Earth has you in its grasps, it won’t want to let you go until you finish all five days…!
But season 4 should work here. The link will take you, I believe, to episode one and there will also be a drop down menu to take you to the other nine episodes.
If the link doesn’t work or you have any problems, let me know and I’ll see what I can do to help!
