That could actually be good scene near the end of the game. If this is something Deep would add to the game I really hope he gives her a very fitting and sexy lingerie underneath the wedding dress.
I didn't really mean it seriously. But if there is a 'Renaissance' route ( And Awake has only said they've been thinking about it, so it's only hypothetical at this point), then maybe we could get a final wedding scene suggesting Anna and Andrew are going to have a happy married life, as well as a naughty one like I suggested above, with the implication things are not going to run so smoothly, with Anna still being tempted sometimes to fall back into her old ways.
But yeah, she definitely has to wear some really sexy lingerie under her wedding dress. Regardless of whether it's on a Renaissance route, there will be a wedding scene eventually in at least one of the endings.
