Serena spoke to me about the mysterious Team Flare grunt in Geosenge Town, then she left. I left town as well and went to Route 11. I encountered Gym Leader Korrina again on my way out of town and I had to battle against her and her two Lucario. I used Litleo to beat the first one with Ember and then I switched to my own Lucario and beat Korrina's second one with Power-Up Punch. Korrina spoke to me some more afterwards and returned to Shalour City. I explored Route 11 afterwards and I battled a Psychic and his Solosis and Sigilyph. I then picked up a Sitrus Berry off the ground by a berry tree and beat a Battle Girl and her Mienfoo with Aerodactyl's Aerial Ace. I then explored the tall grass in the area.
