I'm not sure if it was adressed already, however, but I wanna clear a misconception that I read a few pages earlier. There's no recording whatsoever of other infected people like Ellie being present, or to the Fireflies' knowledge. The recordings you people allude to are referring to Ellie herself.
It gets confusing because Naughty Dog butchered a bit the time between Joel gets knocked out (in real life, such a knock out would make you wake up in a matter of minutes, but Joel spends approximatedly hours unconscious) and when he wakes up. Marlene's notes, and the surgeon's, are referring to Ellie alone.
That does not change my choice, however.
