Scar sensed that the farming community was in danger so he rounded up XenoPred and his runners and told them to help him drag the facehugged Yutaja with the Royal Facehugger to a nearby city that was quit large and had many sewers where they could build their new hive with the new queen.
So Scar and the remaining Xenomorphs that had not went to destroy the town dragged the facehugged Yutaja through fields and forests until they reached the outer city where they found a manhole and entered the sewers.
(The Royal Cestburster should come out of the Yutaja in about five or so posts and all other Xenomorphs besides me, XenoPred, and the made up runners are in the town fighting the predators and killing the human. And the military troops just arrived at the town)
