I’m stuck after you beat the 8th gym leader (Marlon). After you beat him, Cheren says something about Route 21, then heads off. I assume you’re supposed to advance to Giant Chasm, but when I get inside, a few feet forward I’m blocked by two plasma grunts. They say that the people heading to Route 21 are important. I went to Route 21, but nobody’s there except trainers. What do I do, Great Games Guru?
Games Guru: I love Pokemon. But this is so complicated and detailed that I’m going to send you to a walkthrough for help. Otherwise, I would spend a day explaining it to you, and I have more questions to answer! http://www.gamefaqs.com/ds/661227-pokemon-white-version-2/faqs/64482?page=7#section764
