Unless I completely misunderstand how this works, I think 5 is the only one that will fill up. It then overflows, preventing any of the taller ones from filling. 7 is shallower but won't start filling until 3 gets fuller than 5, which it never will. This would be true whether the blockage between 2 and 3 is a mistake or not.
Please help. I have nightmares of being in a room where everyone else is just waiting patiently for me to remember the thing I forgot/figure out what is happening.
The comic used to be big in the ~2000s nerd space, mostly by being one of the earlier video game focused webcomics that hit it big. The author had/has a.... polarizing personality and the comic itself went from dick jokes and game references to super serious miscarriage storyline at the drop of a hat.
