Bonus comic: Disconnect 2 (Patreon)

Talita and Gillie find ways around their communication gap. :^)

Centaurs can make a subsonic booming noise through the air outtakes on their sides. This is below normal human hearing range, but can cause noticable vibration in closed quarters. Talita didn't grow up among centaurs and doesn't know any of the boom-speak languages, but she will sing to herself when alone. Gillie can't hear anything, but appreciates the base-thrumming.

Later in the story, Talita learns some sign-spelling and morse tapping to help her talk to Gillie without paper.
