Several scenarios; some new faded.

Got separated from Bruce Banner as he/we were trying to catch a train for him to follow / engage as the Hulk with an antagonist. Got separated due to the confusing multiple platforms and stairways.

Was followed/watched/checked by some police person, female. Might have been (though don't recall which exact one) a character from tv. At one point she implied that a colleague of hers, male, had messed up or had done something badly.
