Wasn’t there some beatles song about how, um, “he came in through the bathroom window”?

Hey Giga,

I’m neither an expert nor do I have access to the lesson notes but my understanding is that the から is part of the husband’s explanation to his wife for why it won’t be awkward that there is a new boy here despite the presence of Haruya.

Just prior to the part you’re talking about the wife says Japanese to the effect of ‘Remember Haruya is here tonight’ (今夜はるやさんきてるよの) and Yukio interjects and says ‘Oh, a guest?’　The husband responds to his wife (and in a sense ignores Yukio) and replies ‘Oh, that boy, he’s already left.’ I believe the から is because it’s implied within the husband’s response ‘Oh, that boy, (it won’t be a problem because) he’s already left.’ In Japanese the ‘because’ isn’t left out as it would be in English.

(Maybe.)
