Does cw flash k ow speed steal

Ok so I don't know if it's confirmed but when Jay had a idea to get rid of the box he said throw it in the box and then he told barry to take some of his speed the last time barry did this when running by another speedster I don't take their speed is combines their mass or something I got a pic of Jay telling barry to siphon some of his speed

I think the idea is to siphon speed force from another speedster by running behind them and boosting your own speed by absorbing the speed force trail. But I'm not sure.

He knows something that when combined with the current big bad being Savitar strongly hints he'll get speed steal.

Not right now, I think they were just drafting

don't think so

Not yet,just a "rough draft" version.

Whatever it is,it worked with Supergirl.
