Maybe he can tell them he's an orphan and her parents take him in (that is what they did in that show), and they register him in school and explain his situation and Riley just helps him from there for just a little bit? Then we can get to the post where she promises him she'll always be there for him no matter what, and then we just skip six years down the road?
Sure thing, maybe we could have a few posts around school life, maybe him excelling at some sport or something. Just to have it thrown in there, kind of give Riley some doubt about Alex, maybe even just her wondering how?
Replying now. Also, I think now would be the best time to skip forward like you said. I liked that last post, gave me chance to show Alex doesn't know the outside World.
