I thought about the Chief Mouse too, but Rikki-Tikki-Tavi just seemed–I don’t know–more badass. He’d win the fight (unless Aslan stepped again) because he’d go for Reep’s throat while Reep was pontificating about honor.
(Then Giant Wimbleweather would step on Rikki in revenge, so it’s a tragedy all around.)
I wanted to be Batman. Then that sucky-ass TV show with Adam We and Burt Ward poisoned it for me. That’s when I decided it would be better to be Paladin.
