Back into consciousness? It looked like Kongo was out right after Barry dropped him and then Barry jumped on Kongo and woke him back up? Still one of the crazier comebacks I've seen. 
Looks like the first one was behind the ear and buzzed him a little but he wasn't all that badly hurt ,as far as I remember some of the follow up punches really sent him to the la la land and he was on his knees , probably knocked out for like 2 seconds . Ah fk it , it was a mess , I am off to bed and rewatch it tomorrow with my friends for the shock factor as they havent watched it tonight .
