Oh I'm sorry, yesterday and today are busy freaking days. I'm not sure how it's known I think they are guessing.
Yes, the whole group went to Aldo except Cassie & Francis, which really wasn't the plan as Rin & Frederic were supposed to stay with Francis to tell him what was going on. Cassie has gone MIA
Looks like Rin & Frederic were sent back as Mission Control made a mistake, and O'Hara. Also, scans say there are six people in that room instead of 5, so Aipaq? must have made his way there. We're leaving Sam behind to wait for a group headed our way.
We are waiting on result to see if Felicity will die or not. If multiple people volunteer one gets a prize and one dies, but we do not seem to know what happens if only one person tries to fix this leak.
I am worried about him as well. Mostly because at first he seemed to be heading towards a monster room, but thankfully that was a mistake. With Rin back with Francis, she'll let them know what's happening.
