Oh my. Jhon did not realize he was carrying a bomb for several days. And he never found out!

I like your imaginative story, @darthgexe. One thing you could do to improve it a bit more is to make sure you use the pronouns “he”, “his” and “him” when referring to Jhon and “she,” “hers” and “her” when referring to the girl on the train. Nice job!
