I'm pretty sure that they will just go back to showing reruns of Season 1 at 3:30 AM through all of March 2019 as a place-holder for the end of the block, and then in April 2019, then I'm sure that they will bump it up to an earlier time slot and air the 2nd half of Season 3 then. Of course, they might still air old Season 1 episodes at 3:30 AM, and air the new episodes from the 2nd half of Season 3 at an earlier time slot in April 2019. Of course that's just a guess on my part. I guess we'll have to wait and see.
