Trouble? No, Negative Karma? Absolutely(what the Karma does I don't really know, it has to do with Darkrai and Cresselia though). You can also go north from Bill's House to a new area, and there is a hidden area you can get Starters at(and something else with High Karma). Phantump evolves by trade which messes with me every time, be sure to take it to the child in the Goldenrod Inn. You are meant to do Sevii Islands(Mt Ember specifically) for Story Progress.
