You mentioned that he was in the first mage's cabin with the remains of other soldiers.

He checks the remaining doors.

I suspect that Haven is already aware of what happened.

What could the captain possibly tell him? That the prisoners escaped? Okay. If we don't burn the ship behind us (by the way, we can, there's plenty of gunpowder), it will be obvious anyway, there's plenty of evidence. Even if we do burn it, they can still just assume the worst.
And we still don't know where we're headed.

Then that healer would have been killed too.

So, is the assistant's cabin also locked?

Back then, they would have killed that healer too.

Stavros starts breaking down the doors with an axe.
