With Ellen now resembling the invisible man in disguise as a mummy, they boarded a train to Philadelphia, only to find that they would be sitting across from a close friend of Ellen's master, who had known her for years. Luckily he didn't recognize them. Unluckily, he kept trying to start a conversation, forcing Ellen to pretend to be deaf to avoid talking to him. She kept this up for the rest of the journey, probably thinking that at any moment somebody was going to spring out and announce that it had all been a practical joke.
Finally, at their last stop in Baltimore, a suspicious railroad employee refused to allow William to board the train to Philadelphia without proof that he did actually belong to Ellen. However, the other passengers were so sympathetic to the thought of the clearly deathly ill "young man" wandering around Philly without his faithful slave to help him, they insisted that both be allowed to board. And with that, they were free.
