well, it is a Deathstroke book...and the way he's been portrayed.....yeah, not likely.
I'm a huge Jason fan, but I'll admit that him getting dispatched in a few panels wouldn't be out of character for either considering it's Slade we're talking about here. None of Jason's hits, should he even land any, should even register on Slade's person if the fight is written as it should; which is, unfortunately, Jason getting rekt.
If Jason wasn't portrayed so inconsistently, sure, but he is. IMO, the dude should be second to Batman in the Bat Family considering the training he did after he came back.
