Doc meets pretentious performance artist Siobahn, who clashes with Jace and the others. Doc dates Siobahn and irritates the band by bringing her to rehearsals, dressing more stylishly and redecorating his house. The band members finally revolt when Doc tries to make them integrate a sitar into their sound and allow Siobahn to sing. Doc is mad that Jace was allowed to bring in Sarah yet Siobahn is rejected. Jace fights with both Doc and Siobahn. Lucas becomes exasperated with the conflicts and quits, leaving the band without a drummer again.

SlipDog competes in a ""battle of the bands."" The only group the musicians are worried about losing to is headed by a former SlipDog guitarist named Dominic, who they call Dom and who also quit when Jace refused to get rid of Joe. Although he was dating Joe at the time, Dom thought she was an awful bassist. When Joe starts dating Dom again, she reveals the name of the song that SlipDog is going to play. Dom's band then plays that song in the contest arguing that he helped Jace write that song and forcing SlipDog to play something Joe may not be ready to play.
