Ok, I know you use ENTRALINK to get more people in and out of WF/BC, and if you go to a Black version from white and battle trainers, they come to WF, it says so at
http://www.serebii.net/blackwhite/blackcitywhiteforest.shtml#
but there are items that come along with the Pokemon, such as if you battle Backpacker Emi, Happiny and Corphish go into the game, but aside from that, next to the Pokemon is the item Timer Ball. Do you automatically get that item when you talk to that person in White Forest, or what? I want to know this because there are some useful items on that chart, and I want them!
