I have a chapter that I was thinking of starting with a certain sentence - Time began for the passenger now. ( not certain if I need a comma there or not ) I'm prone to write short stories in present tense and unconsciously thought of this sentence in present tense - Time begins for the passenger now. But this is going to be part of a novel and I don't want to use present tense. But I'm not sure the now thing works with past tense. Any ideas? Does it work?
