I think the Dylan/Emma path is, at least for now, the most 'innocent' GF path for Dylan (and - let's admit it, that's why we are here after 6 years ...
). Sophia is trying to push them together under the auspices of helping with certain subjects at school.
I don't see this relationship keeping up with the Dylan/Amber route or, on the gf route - Dylan/Marie.
Dylan might be allowed to Admire the fabric, from across the room, but there will be No fabric touching ... it's too soon...
I feel like Emma is actually being kept in the wings for potential lesbian path encounters where a more confident Sophia can comfort Emma who grows to like Dylan a lot more than he likes her, and who did this favor For Sophia.
If this is not the case, then this is another story branch that could be pruned so that the rest of the tree can grow better/faster.
