My opinion on the Aiden story route is not kind. To make it so prominent... Others might love it but I really don't care for it. It seems to be sold as a necessary function, but I see other more believable routes, I am just not buying it. However, It is L&P's story and we will see what he does.
It is nice to know that you do agree that Dylan's current presence on that path is an obstacle in the storyline. Generally for things to happen, Dylan has to be moved out of the forefront of her mind.
Boarding school has many advantages and benefits for Sophia, Dylan, and the storyline in general. It is hard to find someone that wouldn't benefit.. other than Aiden.
Again, it will be interesting to see what L&P actually does and what routes could be taken.
