I like Francis, he looks to me like a smart guy. Being an investigator by trade will surely help us in finding the solutions to the riddles.

Dain, Percy, Freyja, are all good choices as well.

Morwena and Cronkite strike me as good leaders as well, even if they do not want it.

Splitting into two groups does seem like the most plausible explanation since we are selecting two leaders.

Anything could happen however. We should not always take everything at face value. We have to evaluate all possibilities and investigate and discuss all avenues. There are some other possibilities, but those are more unlikely at this point in time and require more assumptions to be made.

But Occam’s Razor and all that.
