I can't buy the "seduction" motive for either Eli or Abby. In Eli's case, I think the initial reaction to Oskar's request "for a chance" rules that explanation out. If I remember correctly, Abby's reaction wasn't as adverse as Eli's, but I seem to recall that her reaction was more of exasperation rather than "aha, I have him". Abby was shown to be very capable of using her wiles to entrap a victim (the incident with the jogger), but I don't believe there was any ulterior motive in disrobing and getting into bed with Owen. She no doubt needed company after the death of her longtime companion, and its seems logical that she would take off her soiled clothing.
I will say, though, that while it's probably no big deal for Eli to get into bed with Oskar in this manner (as this is Sweden, and Eli is a boy), it's somewhat of a bigger deal for Abby not to at least ask for a T-shirt or something before joining Owen in his bed. In the United States, what Abby did wouldn't be considered such an innocent move, although we are talking about an individual who hasn't exactly led a conventional life. While I applaud the decision to keep this scene pretty much intact in a U.S. film, I think I would have liked to have seen more of a reaction from Owen. Personally, I would have been gobsmacked in that situation, but that's just my opinion.
You're right of course. That's what we get for going off subject.
