My patrons voted for little side/extra comics and they chose an au (inside another au lol) of black and slim meeting back when black was a little baby demon. This is not in the cannon I’ll be working with (at least not till the end there) but baby so fun. i tried to imply a darker reason Gastor didn’t let them meet which i might revisit later in the plot.
Bonus for the REAL reason he wouldn’t let them get together
