You go to Nicolas Telsa's room and talk to him in your porter outfit. After that he will ask you for Prune Juice. So you go to his dressing table and take the glass of prune juice.
The prune juice is in Tesla's room. Change into the clothes of the porter to get inside Tesla's room.
When you get back on the train after the unscheduled stop, go to Edison's cabin. A magnifying glass will appear near your character and the stains will become part of your evidence.

You talk to the lady in the luggage cart and she will say to put on the porters uniform that you will find in the porters closet put that on and go to Tesla's room to give him more prune juice!! (: tee hee
Although the porter throws away the order list, the writing has made an impression in the pad. Pick it up and use your pencil to shade the empty page, and you will find that Tesla ordered the prune juice.
Because the porter won't tell you who ordered it, and throws away the order slip, use the pencil to shade her order pad, and you can see what she wrote. Nicola Tesla was the one who ordered prune juice.
Tesla will have a cup already with him. All you do is click on the pitcher on the dresser, then on the cup to refill it..
After you dress up as the porter on Mystery Train Island, you go in to Telsa's room. You grab the prune juice on his dresser and give it to him. Then he goes to the bathroom and you need to find his luggage key to check his suitcase. It is behind his poster down left.
It is just outside Edison's cabin. You discover it after talking to Mark Twain, as the train makes a sudden unscheduled stop.
You find spilled prune juice in front of Thomas Edison's cabin. When you discover that Nicola Tesla was the one who ordered it, you have to check his cabin. In the luggage car, Mlle. Moreau suggests posing as the Porter to get to Tesla. Go to the Porter Closet and get the extra hat and coat that is there (you just need to wear the cap). Go right to Tesla's room. He will let you in and ask you to pour him some more prune juice from the pitcher on his dresser.
