When you consider the personalties and nature of the synthetics who have names that sound like start-up death metal bands, then you realise that, yes, every synthetic in this strip somehow has a cute (even if ironically cute) name. I mean, look at Swordsmary! She tries to be edgy and punk but she comes across as a nervous undergradute who really doesn't want to cause a scene!
Calling it here: Sam's English teacher is the most vanilla, conventional and unspectacular person you could possibly meet. She sees no reason why her name should be considered 'ironic' or 'inappropriate'.
Maybe someone can help me by directing me to something about 'Millfeeul'? I tried a Google search and all iI got was my local community theatre, the name of which it is a plausible misspelling!
