If Carmen could have any one item from home brought to Johto, what would it be? (Assume Johto restrictions apply - something that can be carried by either the person or the person's Pokémon; no magic, weapons, modes of transportation, or magical weaponry that can serve as a mode of transportation.)

And along those lines, if all of your characters could bring one person from home to go on a Pokémon Journey with them, who would it be?

For both questions, the unspoken "why" is optional but would be appreciated if you would like to provide it.
