yeah but he says the thinness is cute, and shadow chase is supposed to be Perfect for him, isn't he?
You originally failed to mention tulpa Chase....
Regardless, if perfect, then why did Leo make his statement? Tulpa Chase represents the past that Leo clings onto; hence, the physical thinness and missing goatee. Despite the fact, the tulpa is also present because sometimes Leo desparately feels he wants Chase around. You can call someone cute (a subtle attraction), but then you also want them to be hot by [insert activity here] (a profound attraction).
the first quote is about tulpa chase, i thought that was enough. in jenna's route's version of the telling chase about Pretending, he says that it was what he wanted chase to be, which is why im inclined to think he likes thinness, but that's the contradicted by the too skinny comment from carl's route
