I've seen a few articles now that have quoted a passenger who says a cast member told her that she (the cast member) saw the girl climbing. That seems like a bit of hearsay. I'm not saying it's right or wrong, but I'm going to take that with a grain of salt. People love to seem 'in the know' and will sometimes twist things (sometimes unintentionally) to appear that way.
I saw it on the EBTA. We had a medivac situation the night before Lisbon. The WhatsApp was full of contradictory information-some said it was a kid who had slipped and fell the day before, other said it was an adult who had a heart attack. Well it can't be both, and it might not be either. Someone even said their dinner servers told them it was a passenger with a heart attack-I have a hard time believing servers would give out kind of info. I'm not saying people are doing this maliciously, but when something big like this happens and we don't have a lot of info, it's human nature to try to fill in the gaps to make sense of it.
Also, if a cast member did see this girl climbing on the railing, why didn't she take action? I'm not blaming the CM by any means, but it seems odd that the CM would admit to a passenger she saw the girl climbing on the rail but (seemingly) did nothing about it. I feel like something's missing here.
