3.6 - Andy, you said you liked messy, well this is me, messy. I made a mistake. I went about it the wrong way.
4.13 - I can’t be here anymore. With you. I screwed it up. It’s my fault. I screwed it up over and over again. More than anything in the world, more than anything I could ever want for myself. Andy, I want you to be happy. And you are, with him. And that means, I gotta go.
Lots of info in this one. As well as SPECULATION on the rest of the 22 episodes and future seasons.
