I found a really good scenario on MB’s return on TLV FB page: (from MN - sorry if you are in this group)
I am slowly listening to all of the new ones, so far number 1, here I hear a Mum who is worried about her daughter Sally, Threadbo disaster was giving out only the Christian names of Stuart and a Sally were trapped, now Marion message Sally on the 30th and didn,t get a reply, Think by now Panic would had set in and Marion booked herself on a flight to return to Aussie via Japan, where she rang from a pay phone and found out that Sally was okay, but decided to continue her journey and arrived home on the 2nd August. I would had thought she would had tried to contact Stuart or Owen, at the same time she first rang Sally, but what this tells you is that Marion cared about her family although she had a different name she was not going to lose touch with her family no matter what her plans were. As for Blum, he was already back in Aussie, gosh he would had panic thinking he had dumped Marion in England.
