It never turns out well.
Anywhom, even Grendel has a home, has clothes outside of his lab coat, and sleeps. Yes. Sleeps. And watches TV way later than he should, and it affects his dreams. This is the first time we get to see Grendel outside of work. Not Cookie, but Grendel.
He's normal. Kind of.
I wasn't sure what else I could do to add some more flair to his personality, but I'm sure there's plenty of time for that in the future. Also... always use super cool new technology on villainy! It would make the world way cooler! People would be forced to use super cool new technology on superheroism!
Let's change the world, folks!
