The fact that Glenn felt the need to ask Maggie’s permission first before shooting one of ‘em walkers! OTP! :”>

Maggie: My dad’s gonna kick you guys out now, he told me.
Glenn: No, Rick’s gonna work something out with your dad, ok? I had to tell them.
Maggie: You did not!
Glenn: No, I did! Ok, I wanted to! You see, I forgot, ok? I forgot, or I stopped thinking about, or maybe I did’t wanna think about it. I let them lower me into that well like it was fun, like I was playing Portal- It’s a video game-
Maggie: Of course it’s a video game-
Glenn: And then the pharmacy happened yesterday, and I realized something: I forgot that they’re dangerous. I don’t care if they’re sick people or dead people, they’re dangerous! And then I realized something else: That I don’t want you in danger. Ever. So I hate to blow your dad’s big secret, but I’m sick of secrets. Secrets get you killed, and I’d rather have you pissed off at me and alive, than liking me and dead…so that’s why I told them.
Maggie: Hey, Walker Bait.
Glenn: Don’t call me that.
Maggie:Ok, Glenn.
