The water construct is keeping people from falling out on the boats even as both ferry's seem to be taking on water. Erin is trying to split her focus to pull water out of the boat but it's very hard because people are yelling and it's a great deal of water to move around. Then she gets the idea to turn the octopus into more of a water shell so she's moving less water at once.

It works.


But this is a huge mess.
