Yeah, we can do that. One person's meat is another one's survivor, I guess (to torture an expression 'til it squeals), and it's not like I won't be watching next season!
I like the idea of them being taken in their sleep, though. The whole disarmament thing bothers me mainly because yeah, they disarmed Rick and Co...but then promptly gave them their weapons back. Could be that different rules applied to the groups, given that Rick's group was limited to pistols, a crossbow and a katana while the others had rather more serious bits of kit - but if Glenn's mob had their weapons returned you've got a couple of scenarios, each as unlikely as the other: 1) the Terminus lot did the herding thing, very high-risk considering the firepower Glenn et al had, or 2) they willingly laid down their weapons and walked away...which would be fine, I guess (though in that world, I'm trusting no one I haven't known for ages - and maybe not entirely even then), but for the presence of the soldier, who would have been trained better (I hope) and wouldn't have meekly handed over his weapon to a group of unknowns. All in all, drugged food or simply waiting for them to doze off would have been a better, safer option for the Terminus crew and would offer a better explanation.
Either way, it didn't need to be shown, but a couple of lines of dialogue would have done the trick. Waiting until next season to find out something so relatively trivial...nup, just get it done. It's not suspenseful, just annoying - the difference between a wasp buzzing around in your eyeline (will you get stung? suspense!) and a gnat (annoying!).
Having watched it back for a second time, the thing that really bugs me about Joe's demise is how similar it was to the Governor. Back before the mid-season break, you had those eps catching up with his story and throwing out the idea that here, maybe, was something new - a strand showing his redemption, etc. Of course it didn't take long for him to revert to type, but offing the one guy who knew him better than to fll for his 'nice' persona still made sense
if he wanted to really bury the past.
Good actors were cast in the new group (they must be lining up just to appear...) and then...gone. Done with. That two hours you spent watching the catch-up stuff? Gone for good, and it really added nothing to the character in the end.
It's the same trick with Joe and his lot. Bring 'em along in lengthy bits of an ep or two, get you wondering, then have them gone inside a few minutes. It smacks too much of padding to get to the episode count, laziness, or both - though at least the final ep with the Governor ended in a satisfying way and advanced the story.
I was wondering too if the Terminus group were going to separate any kids from their old groups and assimilate them into their own. That might not happen, but if it did...isn't what Carol did a shame?
