While Juan (John in the English version) is looking at the family photo album, rain is heard and water streams down the middle of the window pane, but it is evident that there is no rain falling beyond it.
There's no reason why the neighbors would have stopped to speak with Juan (John in the English version) in the apiary on his way home after the asylum. It's before anyone else is aware of his return, and the incline down from the road was too steep for them to just happen to have noticed him driving by, the direction they were going.
