Video description indicates that they are keeping Impulse's comic book origin that he is a time traveller. Also video preview on World's Finest indicated that the Kroloteans were studying humans to harness the meta-gene, so it looks much more likely that Tye from last episode will be this series Apache-Chief, though probably under the thrall of the Light in the beginning. Wonder how they will explain why Impulse choose that moment in time to visit, especially since him arriving earlier could have solved a lot of problems for our heroes (not a criticism despite what it sounds like, after all one of my favourite books "Guns of the South" explained why the time travellers didn't come to aid the south before the Battle of Gettysburg).
