Ten’s scheduling is all over the place. Why screen Riptide as a double that week and drop So Help Me Todd for a week?
Why didn’t they just start Riptide last week and screen it for four weeks in a row?
They started So Help Me Todd the week before at 9.40pm. Then last week it was a double episode from 8.40pm. Back to 9.40pm for two weeks and the dropped for a week. 
No consistency.
