You can't save the plaaaanet.
With support like that, one wonders how Keen doesn't just toss up his hands and let Mortimer have his way with them all.... (I suppose that nearly happened in canon....
At least he got his macaroni.
For some reason at first glance Lily looked teenager age to me. Probably something to do with all the detail in and around the face.
About the name of Keen's brother... (I'm a bit unsure whether I should post this here or on your site since that's where it's mentioned, but I'm already writing here) there isn't a canonical name as far as I know, but if you want suggestions, maybe Don? There was a time when I thought that was the name of Keen's brother because I didn't fully understand the phrase "Billy dons his brother's football helmet."
By the way how did your nonverbal Mortimer give his mission to Lily? Text message?
