From the conversation between the old man and Johnny, Luke knew that Johnny wasn't the first Ghost Rider; he was just the most recent one.
And Ghost Rider had a special trait, which was that he usually only appeared at night.
Johnny was just human during the day, and didn't have Ghost Rider's terrifying power.
In other words, Luke had nothing to do during the day.
He stretched and went downstairs for lunch.
The street below bustled with activity. There were police officers, forensic scientists, firefighters, reporters, and onlookers.
Suddenly, he saw a familiar person.
She wasn't tall, had a wide girth, and was dressed a little eccentrically. She was the woman whom Ghost Rider had rescued from being robbed under the overpass last night.
She was a little plump and didn't look very old.
