Answer:
Mr. Brownlow is a very respectable-looking elderly gentleman, who has had his heart broken many times, including losing his fiancee on the day of their wedding. He takes a liking to Oliver even after suspecting him of stealing his handkerchief, and takes him in, doing everything he can to help him.
He begs the magistrate, Mr. Fang, to consider Oliver's innocence over simply "looking guilty". I think Oliver faints on the pavement looking pretty out of it. Mr. Brownlow orders a coach to take Oliver away.
