I had many problems with this episode.  The first is the sound effects at the beginning - wind sounds that continue the same amount even after a door is shut (is it blowing inside the house?), but this happened in many episodes.  The second was the husband - sure he pines for his wife, but trying to make someone ill or injured to lure her back?  That's not a good kind of love.  Third was the wife - she's just "separated" from him and already meets someone and wants to go away with them leaving her son at home (we don't know anything about him, either, just that he exists).  She's not the best wife nor mother.  Finally, the mother-in-law - she is fine staying with her son-in-law to watch her grandson (which could be considered admirable), but is also fine when her daughter says in the few days she's been away she met someone and wants to leave with him (no mention of whether or not she'd take her son).  Definitely not a family friendly story nor a very good one.
