"The Speed Force doesn't belong to anyone, if anything, it's the other way around," Bart said, and there's a weight of experience behind that statement. "Thad thought that way, too. He's kinda my brother, I guess, but he's all Thawne. He said I stole the power from him, and didn't care if he nuked the entire west coast if he could get his connection back."

He was almost right, because Bart being the Speed Force as that older him that he remembered being had meant it wasn't available to anyone else.
