You're not wrong but there have been a significant progress between him and Sophia. In the last update i think people forgot that dylan boldly confessed that he desires for her and Sophia was kinda turned on by that also i always say that the relationship devlopment between sophia and Dylan/Elle Will be different than other characters because they're parent and child, you have to understand that. Sophia getting attention from others doesn't mean much, they're different paths. even for Sam, sophia will try to end things with him much later in the game because she fears that it could ruin her family. This update could lead to something imo.
