Even if the Slowbros do seem to be shameless rip offs of NIS's Prinny routine, I am indeed cheering for them. Sadly, being a Watchmen analogy I'm afraid we know how this will end.
Though of course not being the comic writer my sense of humor would probably have the Slobro simply pull out a gun, shoot him, and then instead of letting him roll over and show "oh gee he really did catch a bullet" saying "I saw this movie once..." before shooting him like 40x while he's still down.... which is the sensible thing that nobody seems to remember to do in any horror movie where it would make a differance.
... besides, if Gabe loses this, then any hope for "Episode 3" vanishes for those that care. As a result we can pretty much predict how this will continue.
