Which is why I think Sam would go after BL after figuring out BG's shield can't be penetrated by him. BL can block bullets, but deflecting a man-sized object going as fast as Sam can is outside his power set, I believe.
With BL down, I think Bobby and Sam could come up with a way to take down Booster's artifacts.
BL Has more experience then Bobby? I dunno about thatThe battle turns on the strongest and most experienced guy, Black Lightning. He'll be the last man standing.
