Note the witch used her truename and her superheroic nom de plume in casting the geas on Ronni, after all. And Ronni really never gets a lot of use out of her last name. I always liked the simplicity of it, so this is a perfect chance for her to choose it as a castoff name that she'll respond to easily.
Love the giant heads on pikes. And pig latin for the win, right?
The Earl of Scot's dialogue clearly owes some homage to Army of Darkness, because somehow that riff just runs through this entire issue. I like how he doesn't want the giants defeated or stopped or driven off, he wants them humbled. Nice guy, right? See, this is why we don't have giants anymore.
