In the latest episode of The Flash, Barry Allen goes up against Farooq/Blackout.
In their initial meeting, Farooq drains Barry's speed force almost completely. So, naturally the answer is to give him an electric shock to return the connection...............Anyway, as is revealed, Barry actually gets his powers back, but ends up doubting himself (again) so much that he gives himself the yips. Suddenly Dr. Wells is placed in danger and the yips go away. However, Farooq manages to drain Barry's connection again but overdoes it, but it's different this time because Barry somehow retains his Speed Force connection this time. So the question is, when he initially got the connection drained...
Did he actually lose his powers, or was it all in his head?
How was he able to keep the connection active the second time?
