>>18822855I doubt Stolas is willing to abandon his new lifestyle (how else is he going to get off? even if his gut is now an erogenous zone I'm sure he'd need more than belly rubs to get off), so I'm struggling to think of further ways he could reassure Octavia that he's not going to disappear or abandon Octavia thanks to the disease.
Maybe doing small things, like when he takes her out for dinner he restricts himself to a very small meal, or no meal. Makes an overt effort to make himself look respectable and somewhat manage his appearance (no very loose fitting clothing like picrel). Being confronted with picrel would not leave a good impression but if he's well dressed with clothing to de-emphasize the gut, it'd help.
Just small things. (for a big guy)
