Invisibility Pill

The Invisibility Pill is an item that appears in Stealing the Diamond during the Unseen Burglar pathway.

Role
In order to sneak into the National Museum of History and Culture, Henry needs to pass a guard on the rooftop. He can do this by taking the invisibility pill, which turns his body invisible, allowing him to walk past

In the original game, it backfires as Henry also loses the ability to see, and doesn't know where the entrance is, so he falls off the roof to his doom. This leads to a fail.

In the remastered version however, due the added rooftop wall, the fail scene has been changed with the camera loses Henry's location, and thus can't follow him further into the game.

Fail Message
Original: It's hard to see when you're invisible, no?

Remastered: What happened? I lost track on you!

Trivia

 * While it can be confusing why Henry couldn't see after becoming invisible, this is explained by science. For something to be invisible, light has to pass through that object and not reflect off it. This involves all parts of Henry's body, including his eyes. Technically, no part of the eye can work without light refraction, which doesn't happen if the light passes through the whole eye.
