Very good points, all. I was arguing with my husband last night (at 1:30am, ugh) about the in-characterness of proper!Doctor's decision to take them to the parallel world and leave them. Husband thought it was too pat and contrived, but I thought it was exactly right. Proper!Doctor knows (or believes, anyway) that if they stayed with him, Rose would choose other!Doctor and he'd have to watch. He is often high-handed in making decisions for Rose's own good. He did it in PotW and DD. So yeah, agreed.
