Now some of the commenters above have stated their opinions about how it may be arguable that the act in question may not have been an outrage of Lain's modesty given the context of a session. Now while it is true that the police/prosecution and/or courts may take this interpretation should the act have been committed in the middle of a session, it is clear that this act occurred after the session had lapsed and he was in the process of exiting the room. Given that Lain had not consented to allowing him to perform such an action on her, it is likely that this would be construed as an outrage of modesty.

So my advice would be to be careful when you come out to play and don't land yourself in unnecessary trouble with the law.
