Remember way back in "Vatos" when Rick and co. are going back to the camp, but they find their van missing and they all just assume it was Merle, planing revenge for being left handcuffed on that roof?
Well, it seemed pretty important then, yet afterwards they all just forget about it. Andrea doesn't even mention it once she finds Merle again, in spite of the fact that, if he did steal the van and then lured the walkers to the camp, he was the one responsible for her sister's death!
I hate it when a plot point gets abandoned or completely forgotten before it gets solved.
You guys know if this was ever addressed by Kirkman or Darabont or anyone?
