Grub

Grub Sauce is some liquid related to trolls but appears to be different from blood or sopor slime, such as when Terezi samples some liquid she found on Kanaya's dead body after Eridan flipped the fuck out and attacked Sollux and Feferi, thinking, "please be grub sauce, please be grub sauce," etc. the audience assumes instead of blood. Given that troll reproduction/growth includes a grub-like stage, and Dave's mention of a plump fuck-grub (or something along those lines) to one of the trolls elicits a disgusted response, the nature of grub sauce is dubious. Could it be the mysterious genetic material that is collected in filial pails? Is it just some other troll body fluid? Maybe someone will take mercy on this stub of an article and tell us? Probably not.
