I finally stopped being lazy and continued this challenge. Since I made most of this progress MONTHS ago, I'll be giving the condensed version. I taught Gloom Cut and proceded to defeat Volkner. With Graveler, victory was pretty easy. After that, I took my second Pidgey out of the PC, so that way my roster would be filled up. I killed an Ekans on Route 9, since I already had one. Then King was killed by a Spearow. Meh. I soon caught a Spearow on Route 10. I was hoping for a Onix in Rock Tunnel, but sadly, I encountered and Geodude a defeated it. I left Rock Tunnel without further incident, and I arrived in Lavender Town.
