Luke was very satisfied.
John was very good at solving cases, but his shortcoming was that all his talent went into this one thing, so he had no hope of being promoted.
The thought flashed through Luke's mind as he went to the subway cars and opened them.
The passengers inside were terrified, but they still struggled to get up and head for the door.
However, there wasn't a scramble.
Batman was standing outside, and served as a psychological anchor.
The explosion in the subway tunnel had been a lot more powerful than in the subway station.
Without Batman, the people in the back half of the train would've been heavily injured or killed, while the passengers in the front would've been seriously injured.
It was all thanks to Batman that nobody was heavily wounded or killed.
Of the 20 passengers in the rear car, half had been thrown to the front by Luke, and the other half had seen him block the explosion with his body.
