In the books, the Pensieve makes you feel like you're actually in the memory, but are a powerless observer. The magic of comics will allow me to just show you the memories directly.
In the books, the Pensieve is silvery, but here it's pink/purple like Legilimency. They both involve looking in someone's mind, so I wanted them to be the same color, and it fits into my general color symbolism better.
Other than that, the Pensieve works the same way it does in the books.
