When Bonnie points out the shadow, Ena immediately spots it and she feels her heart sink into her stomach. That was a bad feeling if she ever had one.

Though she'd stopped rowing, the boat was still gliding along the surface of the water, either because Bonnie was still going or simply from the momentum. But after a moment, there's a deep crunch sound and the boat almost comes to a sudden halt. Ena peeks over to see the sea literally freezing over rapidly before her eyes. She tries to break apart the ice clinging to the boat, but any water exposed to the air just immediately freezes over again. How were they going to get away like this?

The larger ship was now clearer in the mist, and was heading slowly towards them. The ice is no problem for it, as it just breaks apart as it moves through. Ena leans forward towards Bonnie, hoping the ship wouldn't crash into them.
