Well, Duncan loses it, but says he is going to look for them. He might team up with others or heard about it from them if he links up with a retreat

Going Art Crazy. We hear a Behemoth in the arena. It may have chased the survivors of the Arena rescue mission to the waterworks when they tried to regroup with the survivor there.

We know we have to find details on Michael and Randy there. Skittles has to know the Arena is bad news. Even if it really is 37, there is still more information to come out the other tower.

It is even possible to tie in Sean if he was in on the rescue and subsequent retreat to the water works before moving south to the colony.
