For a civilization that didn't seem to remember much about their past, this was uncomfortably familiar to history.

Shell.

Don was already moving, having shed his suit, determined to survive. Somehow. He had promised Mindy that he'd consider surviving, winning, and hey. He might as well live up to the promise.

Besides, if this ship was supposed to be what he thinks it was supposed to be, he knew what he had to do. Get to the bow, and hang on for as long as possible. Avoid confrontation when possible. And hope to shell he didn't end up in the cold water. For everyone else it would be a slow death, but survivable. Him?

Instant death.
