Yeah, the guy that talked to Darryl was the guy bouncing the Tennis ball around the house, and on the porch, like I said... Same actor. It was noted on the previous TD for that episode that he was a "known" actor (I didn't know him) but it made sense you'd be seeing him again in some greater capacity. Nice that it was confirmed.

I figured it was only a matter of time before a biker gang became some kind of threat because they're out there in force... It'd make sense they'd be survivors.
I knew Maggie had said something about just being tired... I loved her sign weapon. That was bad ass and she should've kept it. Single-blow killer. Tiring, but for 1-3, it's a devastator. Drop it if there's more. Oh, and thank you sooooooo much for that picture... Good god.
I think "taking" from people wasn't on the Governor's mind as much as having a stronger force... Supplies are limited, but the bigger your army, the better your chance at survival and making sustainable supplies. Basically restarting society... the Governor was very much into that aspect of things. Supply stealing is better left to small forceful groups, but the Governor was about having an army, and a safe city that could/would expand and grow... Taking in the old/sick wasn't an issue to him at all.
The bikers seem like takers... They're rape, steal... They don't want a wife, and a life like before. They'll want just to take from those who have. They'd be an issue for sure, but hypothetically a place like Woodbury would've grown to where a group like that wouldn't have been a major issue I think.
That's such an interesting dynamic though... Having all these different levels of evil. Small marauder groups, large structured groups where control at the top is a major issue, but want ideal lifestyles for the situation... Then the possibility of a "bad" version of Michonne running around, capable and content to live by itself, but equally capable of murdering and pillaging by themselves... True survivor, who's so mentally off anyway they prefer being alone and that society has collapsed.
I think Rick really had the Governor as more a parallel then, to himself, than say these bikers... They're maybe more like a parallel of the military group that was roaming around, who maybe wouldn't have destroyed Woodbury if they'd arrived at it unharmed, but would've perhaps taken it over because they're now the dominant force in it, and run it their way.
