Of course, that is just some speculation, and Todd Helbing could mean they did tinker with The Thinker a bit to make his character fit better into The Flash's Arrow-verse. (Side note: Tinker with the Thinker should be a tie-in web series.) How those changes would be introduced remains a mystery, although we do know for sure that Team Flash does use a cerebral inhibitor against him at some point, thanks to Savitar and his prescience. That would appear to confirm that the telekinetic and mind control abilities he's utilized in the past will be present in The Flash Season 4, which would make the above statement a little more clear.
