Once Team Plasma had left the building in Castelia City, I walked across the street and visited the Castelia City Gym so that I could challenge Burgh for my third Unova badge. I had to slip through walls of honey inside the Gym's honeycomb layout while facing off against Gym trainers and their Bug-types. I eventually reached Gym Leader Burgh's spot and we fought. I thrashed Burgh's Whirlipede with Simisear's Incinerate, then his Dwebble with some of Dewott's Razor Shell attacks. Blitzle's Flame Charge defeated Leavanny and next I won the Insect Badge and Struggle Bug TM. I stepped outside afterwards and Bianca called me on the Xtransceiver to challenge me. I dashed towards Route 4 and defeated her quickly.
