Told you the reason why she talked would be important.
So, funny story - while reuploading these comics, I'd actually forgotten why there was a dummy there for Kirby to eat. I just thought to myself, "boy, Kirby eating a dummy is a really lame copout." I completely forgot the punchline for this one as to why it was there. Not that the punchline here is any less of a copout, but it's more interesting at least.
I have no idea why that one cultist is pretending not to hear anything. I'm sure I had a reason.
