I think you might be right on that Nick... They intentionally didn't show that I think. Tyrese maybe hid something. They'd have showed him beat the guy to death if they were going to go that route I do believe.
Outstanding episode, start to finish... I too put it up there as the best opening this show has had since the Pilot episode. Violent, tense, layered (though all in one area more or less). The flashbacks set up some of the Termites and their ultimate return... Like the Governor, you're the way you are for a reason, and they're no different.
Just outstanding.
I'm pretty ok with all the action, even Carol's fireworks display. That's a big propane tank. You don't have to hit much of that with it spewing that much gas. Just a spark, and most bottlerockets pop with a lot of sparks. She also had it fired from that rifle barrel and believe it or not a metal tube is about all you need to launch a bottlerocket with accuracy! Suffice it to say I played with illegal fireworks as a kid, a lot.

(RIP, many GI Joes) I can see it working actually. Though she didn't seem to have random fireworks around her all the time to really know what to do, maybe it was just a good guess?
The final scene, post-credits, was fantastic. People always are asking, and that was a nice nod to fans to throw them a bone! I loved it.
Tracy, I'm with you on Carol. Don't know about if you watch TD all the time but they polled people on Carol taking over the group since she showed clear leadership skills here, and she lost miserably, but I was honestly thinking she maybe should be the group's leader. Biggest problem with that now though, is she's one of many. Rick's obviously in a better leadership position when he's in Shane-Mode like now, Abraham's not a poor leader... Glenn's emerged a little (and where there is Glenn, there is Maggie), but not completely. Sprinkle in a dash of Darryl and Sasha too... I think the group's back to group decisions to some degree, but much more intelligent group decisions than before.
And if I may say, Conan's the finest non-show guest they've ever had on Talking Dead... Seriously. "I'd have died on a sunscreen run". I lol'd.
