Leaking gas appears to have caused someone to collapse. Had they been working in an enclosed space (like a broom cupboard) this sort of thing is quite possible. As it is, the room they were in has a high ceiling and could hardly be better ventilated; it is extremely unlikely that a leak of bottled acetylene in that space would cause anyone to pass out.
Laura quotes, "'Music is the wine that fills the cup of silence' by Robert Fripp of King Crimson." The quote is from Robert Fripp, but Robert Fripp the critic and author, not Robert Fripp the musician who played with King Crimson. [According to the Robert Fripp / King Crimson website DGMlive, the quote should be "Music is the cup which holds the wine of silence" but of course this is a drama, and in real life people do get quotes wrong - perhaps the writer deliberately changed the quote. The past tense is wrong here as well: as of 2018 Fripp still plays with Crimson, as well as offering such aphorisms.]
