[Letha jumps back when he pulls out the gun - it doesn't look exactly like what she thinks of as a gun but close enough to recognize - and her zombie stumbles to move between them, guarding her from Rick as she assumes it's her he's angry at.]

I'm sorry, I didn't realize you disliked this sort of magic! I mean to say- well please don't shoot, I can disanimate it, I really don't want any trouble!

[Being startled made her zombie a bit twitchy, as she's having trouble keeping tight control on it. The absolute last thing that she wants is for it to go rogue.. because unlike most conventional zombies, her kind aren't affected by losing their brains.]
