Drowning
Indy whips away a Nazi’s gun from the train sequence earlier in the trailer, followed by this odd sequence. And, again, apologies for the not-great screenshot, it moves very fast. But someone who is not Indy clearly looks to be stuck or left underwater as someone or something else escapes to the surface. Do Indy and Helena have to kill someone to get whatever they need underwater? If it is them, of course.
