Too late to do that plot now! 
They will have to leave the prison for one reason or another though......
Personally I would love to see more flashbacks of when the outbreak happened, the few that we got were superb!
Also, a few things that have had me thinking a lot about this episode are:
- the gun buried (possibly Carl's gun??)
- the zombie with bleeding eyes
- the pig that died
- notice the boy who died also had blood from his eyes
I definitely think the virus has mutated or/and somehow the animals that they are eating are carrying a mutated form of the virus that will cause death, would explain the whole pig death scene.....
Plus notice how for next weeks episode, Glen says there are walkers in the prison block so either that boy has killed other people during the night (although am sure that people would have heard screams etc.) or others have turned via the same way he did???
Still want to know why on earth Rick is so against carrying/using his gun too!
