We begin with a flashback. Shane (who isn't dead and wasn't then either, alas) is in the hospital where Rick was when he was shot. It's in chaos, being overwhelmed by Walkers. I loved this scene simply because it showed us a hint of how great the chaos was at its peak when the Walkers were coming, people were running – apocalyptic rather than post-apocalyptic. There's gunfire and panic, people screaming. He tries to get Rick out but he doesn't know what to do, how to disconnect him, how to move him. The power goes off, and the machines – it seems that Shane can't find a pulse (you'd think he'd have better training) The building is becoming overrun by Walkers – he blocks the door to Rick's room with a bed and runs. He isn't eaten.
Back to the present day – the gang runs into the CDC compound. The contrast is stunning – the building is in good repair, unworn, not covered in corpse and jury rigged repairs – it's untouched in a world that is ruined. A wonderful symbol for hope.
They meet Jenner and he asks what they want – A chance. An awful lot to ask these days. He demands they all submit to a blood test (pointless but its a procedure they cling to) then locks the place down. And they learn that he's the only one left.
But there are a lot of supplies – and copious amounts of red wine. Which means, since they haven't eaten in days they can have a party. It's probably the first time we've seen them all together happily and it really stands out because of it. In some ways this party communicated more about how hard their lives had become more than anything else by showing this rare moment of joy.
Of course it can't last, not only is Jenner silent and broody in a corner but Shane just cannot let the happiness stand (pouting over partial success of Rick's plan?) and asks where the doctors are – again it seems less about curiosity and more so he can say how wrong Rick is. (Did I mention how much I hate this guy? Something needs to eat him). Jenner reveals that most of the doctors ran – or committed suicide when all seemed lost, leaving Jenner as the last one
They head to the showers and it's like a recap to episode. Hot water – something we take for granted has become such a luxury to them. Everyone enjoys the showers except Andrea in her grief and Shane in his petulance (he still didn't get eaten). Andrea is sick and Dale is there to comfort her. She is utterly depressed with everything lost, nothing to cling to. I really love the bond developing between them – I have seen father daughter teams in other shows that didn't have half the bond as these 2.
Rick decides to thank Jenner some more by making the extremely depressed doctor a little more depressed by telling how depressing and desperate it is out there. He then unloads his bottled up worry and despair on the doc. Which, y'know, fair enough Rick has kept moving kept things together and maintained a perfect aura of confidence for so long now and in such extremely situations of fear, grief and loss – and when you consider that because of his coma he's had far less time to come to terms with all this than everyone else. So yes -0 he's more than due an unload and I'm glad to see it, this takes its toll. But I think Dale or even Jacqui would have been a better confessor (I'd suggest Lori but he's got too much of a protection thing for her and she's got too much of a guilty “I slept with someone else must be perfect to make up for it!” problem). I think unloading to the Doctor with the dead “it's all over” eyes isn't the best bet even if you are drunk on the CDC's infinite supply of red wine (and how much does the CDC have do you think? I mean these are top notch doctors so you know it's not the cheap stuff! Do they always stock it or when the world was ending where the scientists doing Supermarket Sweep in the local off-licence?).
But I digress (it's the booze). Dr. Jenner tells him it'll all be ok in a deadpan “there is no hope” kind of voice before panning back into the depressing and desolately empty main room (I think “it'll all be ok” is probably a lie).
